Daylight saving time
around the world, showing usage and a short history by
location in alphabetic order.
Africa
The only African countries and regions which use daylight saving
time are:
- Canary Islands
From the last Sunday in March to the last Sunday in
October and UTC.
- Egypt
From the
last Friday in April to the last Thursday in September and
UTC+3.
- Morocco
From June 1
to August 21 (in 2009) and UTC+1.
- Namibia
From the
first Sunday in September to the first Sunday in April and
UTC+2.
Egypt
The British first instituted daylight saving time in Egypt during
the Second World War, specifically between 1940 and 1945. The
practice was stopped after the war, but resumed 12 years later, in
1957.
Egypt normally
observes daylight saving time between the last Thursday in April
and the last Thursday in September when the clocks are three hours
ahead of Greenwich Mean Time (UTC+3).
The change is at midnight (local time); i.e. on the last Thursday
of April, one second after 23:59:59 becomes 1:00:00 on Friday.
Daylight saving time ends on the last Thursday of September; on
that Thursday, one second after 23:59:59 becomes 23:00:00. The date
does not change when the first 00:00 midnight occurs; for all
practical purposes, midnight does not occur until after the
second 23:59:59. An exception is made for
Ramadan; in 2006 the end of DST took place one week
earlier, on September 21, 2006, to take place before the start of
the holy month of
Ramadan. This has
continued in 2007, 2008 and 2009.
Mauritius
Mauritius's DST period started on the last Sunday in October, and
ended on the last Sunday in March.
Mauritius did not repeat DST in 2009.
Morocco
For the year 2008, DST began on June 1, and ended on September 1,
2008. This was the first time Morocco had used daylight saving time
since 1978, and it has not been decided whether to use it in future
years. Morocco implement DST again in 2009 starting on June 1,
2009.
Namibia
DST begins on the first Sunday in September, and ends on the first
Sunday in April.
Tunisia
Tunisia adopted daylight saving time for the first time in 2005
starting 1 May 2005 and following EU time schedules thereafter.
This comes as a move by the government to promote saving of energy.
In 2009 the government of Tunisia canceled DST and kept the
standard time all year round.
No DST in Africa
These countries or regions do not use daylight saving time:
Asia
China, People's Republic of
The
People's
Republic of China
experimented with DST from 1986, but abandoned DST
from 1992 onwards. The PRC now uses one time zone (UTC+8)
for the whole country.
Bangladesh
Bangladesh
is using Daylight Saving Time(DST) forwarding one
hour from June 19, 2009. Now the clocks in whole Bangladesh
are seven hours ahead of Greenwich Mean Time (UTC+7).
Hong Kong
Hong Kong used DST beginning in 1948, but abandoned it from 1980
onwards.
India
The
Republic of
India
used Daylight Saving Time(DST) briefly during
wartime. Currently, India does not observe DST. However, in
recent times when outsourcing has become an integral part of the
nation's economy, IT and ITES companies are following it.
Iran
Before 1979, DST was observed in Iran. Thereafter it was abandoned
until 1989, when it started on the first day of Farvardin (20-21
March) in the
Iranian calendar and
ended on the last day of Shahrivar (20-21 September). In the Spring
of 2006, the government of Iran ceased observing DST. In September
2007, however, the
Majlis (Iranian
parliament) passed a law restoring daylight saving time beginning
from the spring of 2008, despite opposition by the contemporary
government.
Iraq
During
2003-2007, Iraq
observed
DST from the first Friday in April to the last Friday in
October. Before 2003, DST was observed from the last
Thursday in April to the last Thursday in October.
Iraq has not observed DST since 2008.
Israel
Israel
observes
DST starting on the last Friday before April
2 and ending at 02:00 on the Sunday between Rosh Hashanah and Yom
Kippur. Until 2005, the schedule was variable: the only
requirement was that there be at least 150 days per year of DST,
and the dates were set out each year by the Ministry of the
Interior.
In territories controlled by the
Palestinian National
Authority, DST ends later, which can lead to some confusion. On
September 5, 1999, terrorists were transporting a bomb that they
mistakenly thought was set to go off at 17:30 Israel Standard Time;
it was actually set for 17:30 Palestinian Daylight Time, which was
an hour ahead. As a result, the bomb went off while the bomb was
still being transported, killing the terrorists (and earning them a
Darwin Award).
Japan
From 1948
to 1951, Japan
observed
DST between May and September every year under an initiative of the
U.S.-led occupation army. The unpopularity of DST, for which
people complained about sleep disruption and longer daytime labor
(some workers had to work from early morning till dusk) caused
Japan to abandon DST in 1952, shortly after its sovereignty was
restored upon the coming into effect of the
San Francisco Peace Treaty. Since
then, DST has never been officially implemented nationwide in
Japan.
Starting in the late 1990s, a movement to reinstate DST in Japan
gained some popularity, aiming at saving energy and increasing
recreational time.
The Hokkaido
region is particularly in favor of this movement
because daylight starts as early as 03:30 (in standard time) there
in summer due to its high latitude and its location near the
eastern edge of the time zone. In the early 2000s, a few
local governments and commerce departments promoted unmandated
hour-earlier work schedule experiments during the summer without
officially resetting clocks.
The Council on Economic and Fiscal Policy is expected to propose
that the Japanese government begin studying DST in an attempt to
help combat
global warming. The
former Japanese PM
Shinzo Abe made a
significant effort to introduce daylight saving time, but was
ultimately unsuccessful. However, it is not clear that DST would
conserve
energy in Japan. A 2007 simulation estimated that introducing
DST to Japan would increase energy use in
Osaka residences by 0.13%, with a 0.02% saving due to
lighting more than outweighed by a 0.15% increase due to cooling
costs; the simulation did not examine non-residential
buildings.
Jordan
Jordan
UTC+2
observes daylight saving time from the last Friday of March to the
last Friday of October.
Kazakhstan
Kazakhstan
made a decision to stop observing DST in 2005,
citing health complications as well as lowered productivity and a
lack of economic benefits.
Kyrgyzstan
Kyrgyzstan
voted to stop observing DST in 2005 and remain on
UTC+6 as Standard Time (which used to be Kyrgyzstan Summer Time),
thus still saving energy.
Lebanon
Lebanon has the same rules as the EU Countries, starting on the
last Sunday of March and finishing on the last Sunday in
October.
Pakistan
Pakistan
experimented with DST in 2002, going from +5:00 to
+6:00 on the first Sunday in April at 00:00 to the first Sunday in
October at 00:00. Pakistan has implemented DST again from
June 1, 2008 to August 31, 2008, to meet the annual shortfall of 4
gigawatts of electricity instead of
enforcing daily power cuts in households and factories. The
government later extended the schedule to October 31, which also
included the holy month of Ramadan, which began in early September.
In 2009 DST starts on April 15, and ends in November 1.
Philippines
The
Philippines
experimented with DST for short periods during the
presidencies of Corazon Aquino (1986
to 1992) and Fidel Ramos (1992 to
1998). DST was primarily intended to help deal with the
country's energy crisis by minimizing the number of hours during
which electric lighting was needed. On April 2006, the Philippine
Department of Trade and Industry again proposed that DST be
implemented to help deal with rising oil prices.
South Korea
South Korea
observed DST from 1948 to 1951, from 1955 to 1960,
and from 1987 to 1988. South Korea does not currently
observe DST. As of July 29, 2009, the South Korean government is
considering re-introducing daylight saving time from April
2010.
Syria
Syria
observed
DST at UTC+3, in 2006 from 30 March until 21 September (a change
from 30 September).Now, DST is observed from the last Friday
of March to the first of November.
Taiwan
Taiwan
implemented DST from 1945 to 1961, revoked DST from 1962 to 1973,
reinstated DST from 1974 to 1975, and abandoned DST from 1976
onwards.
No DST in Asia
These countries or regions do not use daylight saving time:
Oceania
New Zealand, Australia , Samoa
and
Fidji
are
current areas of Oceania that have
DST.
Australia
Daylight saving was first used in Australia during
World War I, and was applied in all states. It
was used again during the Second World War. A drought in Tasmania
in 1967 led to the reintroduction of daylight saving in that state
during the summer, and this was repeated every summer since then. A
trial season of daylight saving commenced in 1971 in New South
Wales, Queensland, South Australia and Victoria. In 1972 NSW, SA
and Victoria joined Tasmania in regular daylight saving. Queensland
had daylight saving from 1989 to 1992.
Currently, New South Wales
, Victoria
, Tasmania
, Australian Capital
Territory
and South Australia
apply DST each year, from the first Sunday in
October to the first Sunday in April. Originally Tasmania alone commenced daylight saving on the first
Sunday in October, while the other states began on the last Sunday
in October and finished on the last Sunday in March, until
2008.From 2008/09 daylight saving has been extended another
four weeks in NSW, Victoria, SA and the ACT, in addition to
Tasmania, from the first Sunday in October to the first Sunday in
April.
In
Western
Australia
, four referendums in
1975, 1984, 1992 and 2009 have rejected DST.In 2006, the
Parliament of Western
Australia approved a three-year daylight saving trial to be
followed by a referendum to decide whether DST should be put in
place permanently. However, public opposition mounted during the
first year of the trial, and the
WA Nationals announced a
public campaign to bring the referendum forward to 2007. The trial
continued until the referendum, held on 16 May 2009. The result was
another rejection of DST, by a larger margin compared to the three
previous referendums.
Although as previously the suburbs of the
state capital, Perth
, supported the proposal, it was by a much narrower
margin than before with significant swings against it in several
areas, most notably in the East Metropolitan
region. As a result, the Premier of Western Australia has
said that the DST issue should not be considered for at least
another 20 years.
The
Northern
Territory
and Queensland
do not observe DST. Queensland experimented
with DST in the early 1970s, and again in the early 1990s, but it
was abandoned after a majority of residents voted against it in a
1992 referendum. It continues to be a source of controversy,
particularly in the highly populated
south-eastern corner of the state
which borders New South Wales, where DST is observed. The Northern
Territory experimented with daylight saving in the early part of
the 20th century. It was last used in 1944.
New Zealand
From 30 April 2007, DST begins at 02:00 NZST on the last Sunday in
September each year, and ends at 03:00 NZDT (or 02:00 NZST as
defined in the Time Act 1974) on the first Sunday in April.
New Zealand time, including DST, is used by several
Antarctic bases that are supplied from New
Zealand.
This results in the oddity that the
Amundsen-Scott South Pole
Station
sets its clocks an hour further ahead during the
southern summer, when the sun is constantly above the horizon, than
in the southern winter, when the sun is constantly below the
horizon. The extreme geographic position of the base means
that no possible adjustment of the daily activity cycle can have
any effect on the amount of sunlight received during those
activities. However, the arrangement presumably makes real time
communications with New Zealand more practical, particularly in
dealing with offices.
Samoa
Samoa starts
with DST in 2010, starting on the last Sunday in September and
ending on first Sunday in April.
Fidji
Fidji reignites
DST in 2009 starting on November 29 and ending on April 26,
2010.
Hawaii
Because
of Hawaii
's tropical latitude, there
is not a large variation in daylight length between winter and
summer. Advancing the clock in Hawaii would make sunrise
times close to 7:00 a.m. even in June.
(Most of the
inhabited islands are located close to the west end of the Hawaii-Aleutian time zone, but
Oahu
, Kauai
and Niihau
are located more than 7 degrees west of the
Hawaii-Aleutian time
zone's meridian and should,
theoretically, be located in the next time
zone to the west.) Hawaii did experiment with DST for three
weeks between April 30, 1933 and May 21, 1933; there is no record
as to why it was implemented or discontinued. Hawaii has
never observed daylight saving time under the Uniform Time Act,
having opted out of the Act's provisions in 1967.
U.S. Territories
All U.S.
insular territories with civilian government in Oceania, American
Samoa
, Guam
, and the
Northern
Mariana Islands
lie in the tropics, and do not observe
DST.
Europe
In general
All
countries in Europe except Iceland
observe DST, and most change on the same date and
time, starting on the last Sunday in March and ending on the last
Sunday in October. Before 1996, DST ended on the last Sunday
in September in most European countries; however in the United
Kingdom and the Republic of Ireland DST ended on the fourth (which
some years is not the last) Sunday in October. In the West European
(UTC), Central European (CET, UTC+1), and East European (UTC+2)
time zones the change is simultaneous: on both dates the clocks are
changed everywhere at 01:00 UTC, i.e. from local times of
01:00/02:00/03:00 to 02:00/03:00/04:00 in March, and vice versa in
October. See also:
European Summer
Time and
British Summer Time
which includes a description of
Double Summer Time.
Denmark
Although DST has been observed in Denmark for the past few decades
and its observance will continue in accordance with EU orders, a
national association against DST (Landsforeningen mod Sommertid)
still exists.
Iceland
With
Iceland observing UTC all year round despite being at a
longitude which would indicate UTC-1, the country may be thought of
as being on continuous DST. Iceland's high latitude means
that sunset and sunrise times change by many hours over the year,
and the effect of changing the clock by one hour would, in
comparison, be small.
Norway
In Norway, DST (locally known by the expression "summer-time") was
introduced in 1916, 1940-45, and 1959-65. The arrangement was
controversial, and in 1965 the Norwegian parliament (Stortinget)
voted to discontinue the practice.However, in 1980 DST was
reintroduced, and at present (2009) Norway follows the European
Union in this matter.
Romania
DST was
originally introduced in Romania
in 1932 (between May 22 and
October 2). Between 1933 and 1940
DST started on the first Sunday in April and ended on the first
Sunday in October. The DST was abandoned in 1941, to be
reintroduced in 1979. Until 1996, with few exceptions, the DST
started at the end of March and ended at the end of September.
Since 1997, DST has started in the last Sunday in March and ended
on the last Sunday in October, per
European Summer Time.
Russia
In
Russia
, daylight saving time was originally introduced on
July 1, 1917 by a decree of the Russian Provisional
Government,and clocks were moved one hour forward. It
was abandoned by a
Decree of the
Soviet government five months later,
clocks being moved one hour back again on
December 27.
Daylight
saving time was reintroduced in the USSR
(Moscow Summer Time) on April 1, 1981, by
a decision of the Council of Ministers of the
USSR, and its practice continues into post-Soviet times.
The
changeover dates in Russia are the same as for other European countries, but
clocks are moved forward or back at 02:00 local time in all
zones. Thus in Moscow (local time = UTC+3 in winter, UTC+4
in summer), DST commences at 23:00 UTC on the day before the last
Sunday in March, and ends at 23:00 UTC on the day before the last
Sunday in October (note that "day before last Sunday" is not the
same as "last Saturday" in a month where the last day is a
Saturday).
Sweden
In
Sweden
daylight saving time was originally introduced on
May 15, 1916. It proved unpopular at the time, and on
September 30 in the same year, Sweden
returned to year-round standard time. This situation continued for
more than half a century.
On April 6, 1980, Sweden again introduced daylight saving time, and
since then DST has been observed every summer in Sweden. Except for
the introduction year 1980, daylight saving time has always started
on the last Sunday in March. It ended on the last Sunday in
September during the years 1980-1995, and on the last Sunday in
October from 1996 onwards, following a unification of start/end
dates of DST within the
EU as well as in several
European countries then outside the EU.
Five days before the reintroduction of DST in 1980, a major Swedish
newspaper took the opportunity to publish an
April fool's joke on April 1, 1980. The joke
claimed that DST had been introduced almost in secret with nearly
no public information, that everybody was late everywhere, that
hardly anyone really knew what the time was, and that there was
chaos everywhere.
Turkey
DST was
introduced in Turkey
in 1947, but suspended from 1965 through
1972. Since 1974, Turkey follows European Summer Time.
Turkey has started working to abolish daylight saving time from
2009 onwards, but due to technical reasons and (and not due to the
opposition from the Turkish Foreign Ministry), has been postponed,
to be abolished in 2011 Turkey proposes to adopt a new time zone in
2011: UTC+2:30 throughout the year (with no Summer Time).
North America
North America generally follows the
same procedure, with each time zone switching at 02:00 LST (local
standard time) to 03:00 LDT (local daylight time) on the second
Sunday in March, and back from 02:00 LDT to 01:00 LST on the first
Sunday in November since 2007. Previously, daylight saving time was
four to five weeks shorter (see
below).
The
Canadian province of Newfoundland and Labrador
is an exception in that the time changes take place
at 00:01 local standard time and 00:01 local daylight time
respectively. Also, in 1988, they experimented with double
daylight saving time, when the clocks went ahead by two hours,
instead of the usual one hour.
Canada
In
Canada
, time is under provincial and territorial
jurisdiction, not federal. Since at least the 1970s, all
provinces and territories have matched their DST start and end
dates to those used in the United States, and when the U.S.
Congress
changed the rules effective 2007 the provinces and territories
(except Saskatchewan
) changed their time legislation to match.
Since 2007, their DST starts on the second Sunday in March, and
returns to standard time on the first Sunday of November, to
coincide with the U.S. dates. As noted below, most of Saskatchewan
does not technically observe DST but rather observes a skewed
'standard time' that has been advanced one hour forward permanently
(that is, observing what is sometimes known as 'year-round
DST').
British Columbia
Most of
British
Columbia
(BC) is on Pacific
Time and observes DST. However there are two main
exceptions:
Part of
the Peace
River Regional District
of BC (including the communities of Chetwynd
, Dawson Creek
, Hudson's Hope
, Fort St. John
, Taylor
and Tumbler Ridge
) is on Mountain Time
and does not observe DST. This means that in winter the region is
on the same time as Edmonton
, Alberta
, and in summer is on the same time as Vancouver
, BC.
The
East Kootenay region of south-eastern
BC (including the communities of Cranbrook
, Fernie
, Golden
and Invermere
) is on Mountain
Time and observes DST. This means that the region is always on
the same time as Edmonton, Alberta. One exception in this region is Creston,
which observes MST year round. Time in Creston is therefore the
same as Edmonton in the winter, and Vancouver in the summer.
Nunavut
While
the rest of Nunavut
observes DST, Southampton Island
including Coral Harbour
remain on Eastern Standard Time throughout the
year.
Ontario
Most of Ontario uses DST. Pickle Lake, New Osnaburgh, and Atikokan,
three communities located within the Central Time Zone in
Northwestern Ontario, all observe Daylight saving time all year
long. (This has the effect of having them on Central Time during
the summer tourist season, and Eastern Time during the winter -
without ever changing their clocks.)
Quebec
Most of Quebec observes DST.
However, the eastern reaches of Quebec
's North Shore
, east of 63° west
longitude, are in the Atlantic Time Zone, but do not observe
DST (see exception, below). The effect is that in summer
their clocks match those of the rest of the province, while in
November, their clocks are rejoined by their Atlantic Standard Time
neighbours. Although places east of 63° west are officially on
Atlantic Time, local custom is to use Eastern Time as far east as
the
Natashquan River.
Those communities
observe DST, including all of Anticosti Island
, which is bisected by the 63rd
meridian.
Saskatchewan
Officially, the province is part of the Central time zone (
UTC-6). This time zone designation was implemented in
1966, when the Saskatchewan Time Act was passed in order to
standardize time province-wide. This creates a situation in which
Saskatchewan is effectively on DST year round. The Mountain
Standard Time line is actually centred in Saskatchewan and the
entire province is within the MST (
UTC-7)
zone.
The
charter of the city of Lloydminster
, which is bisected by the Saskatchewan–Alberta boundary, gives it a special exemption.
Lloydminster and the immediately surrounding region in Saskatchewan
observe the same time as Alberta:
Mountain Standard Time with
officially sanctioned seasonal daylight saving.
Along the Manitoba
border, the small, remote Saskatchewan towns of
Denare
Beach
and Creighton
unofficially observe DST in the central time
zone, thereby keeping the same time as larger neighboring Manitoba
communities.
Greenland
Greenland
(excluding two minor areas at Danmarkshavn
and Pituffik) observes DST
and uses the European convention (DST begins 01:00 UTC last Sunday
in March and ends 01:00 UTC last Sunday in October). Most of
the country is in the UTC-3 zone in the winter (UTC-2 in the
summer).
Mexico
Mexico
adopted DST nationwide in 1996, even in its
tropical regions, because of its increasing economic ties to the
United States. Although the United States
has changed the schedule for DST beginning in 2007,
Mexico will not be going along with it. DST has
often been a contentious issue in Mexico and is not likely to be
extended. Daylight saving time for Mexico begins the first Sunday
of April, and ends last Sunday of October; and is usually refer as
"Summer Schedule".
Baja California
The
state of Baja
California
has observed daylight saving time from several
decades ago and until 1996 was the only Mexican state to observe
it. Its neighbor, the US state of
California
, observes DST a few weeks earlier, complicating
economic ties between border cities.
Sonora
The
state of Sonora
has not observed DST since 1998 because of the
non-observance of DST by its neighbor Arizona
and its important economic ties with the US
state.
Island territories
The
Marías
Islands
and the Revillagigedo Archipelago
do not observe DST. The westernmost
island of the Revillagigedo Archipelago, Clarion Island
, uses UTC-8 (PST) all the time, thus during DST,
Mexico has 4 different time zones.
United States
Ohio Clock in the U.S.
Capitol being turned forward for the country's first daylight
saving time in 1918
Most
areas of the United
States currently observe daylight saving time.
The
exceptions are Hawaii along with the territories of Puerto Rico, the Virgin
Islands
, American Samoa, Guam, and the
Northern
Mariana Islands. Daylight savings time is observed in
Arizona only in the Navajo
Nation. From 1987 to 2006, daylight saving time in the
United States began on the first Sunday of April and ended on the
last Sunday of October. The time is adjusted at 2:00 a.m. (02:00)
local time.
By the
Energy Policy Act of
2005, daylight saving time (DST) was extended in the United
States in 2007. DST starts on the second Sunday of March, which is
three or four weeks earlier than in the past, and it ends on the
first Sunday of November, one week later than in years past. This
change resulted in a new DST period that is four weeks (five in
years when March has five Sundays) longer than in previous years.
In 2009, daylight saving time began at 2:00 a.m. (02:00) on Sunday,
March 8, and it ended at 2:00 a.m. (02:00) on Sunday, November
1.
Central America
Guatemala
Guatemala has used DST from time to time due to energy problems.
The last time it used DST was on April 30, 2006, ending on October
1, 2006. However DST was not observed in 2007-2009.
Honduras
Honduras adopted DST once, from May 1994 until September 1994 but
then abandoned it. On May 7, 2006 it again used DST; however it
ended on August 7, 2006, making this the shortest use of DST in the
northern hemisphere as it was only applied for 3 months. The
government decided not to use DST in 2007.
Nicaragua
Nicaragua observed DST from January 1, 1992 until February 20, 1994
but it was stopped. On April 10, 2005 until October 2, 2005 DST was
implemented, and the following year the period was similar,
beginning on April 30, 2006 and ending on October 1, 2006; this
measure was for energy conservation. In 2007, the government of
Nicaragua decided to stop observing daylight saving time.
West Indies
Cuba
Cuba remained on DST from April 2004 until October 29, 2006. Cuba
was on DST from March 11, 2007 to October 28, 2007 and restarted
DST again on March 16, 2008. Cuba observes DST from the second
Sunday in March to the last Sunday of October.(According to Radio
Relo Cuba will begin DST on Mar 8, 2009)
South America
Argentina
After a
period of not observing DST, on December 21, 2007, Argentina
resumed observance of DST in some provinces in an
attempt to save energy. For each period, the executive
branch must set the specific start and end dates for DST, i.e.
there is no fixed annual schedule.
According to World Time Zone
(http://www.worldtimezone.com/dst_news/dst_news_argentina07.html),
there will be no DST during the 2009-10 season, the entire country
staying on UTC-3. Below are the translated news headlines:
10/15/2009, Argentina - "El Gobierno no cambiaría la hora oficial
el próximo domingo"(English translation"The Government would not
change the official time on Sunday"), InfoBae
The Clock will not be changed in Argentina. The Government will not
go ahead with the measure (DST), probably because the disagreement
across the country is very high. Capital Federal and Misiones were
solely for the advancement of 60 minutes.
10/15/2009, Argentina - "AL FINAL NO HABRA CAMBIO DE HORA"(English
translation "THERE WILL BE NO CHANGE OF TIME IN THE END"),
DiarioShow
Finally, the national government decided this year not to advance
clock, which had been implemented in recent years to bring
electricity consumption in summer time and take advantage of
sunlight.
Brazil
Brazil
adopted DST (called horário de verão –
"summer time" – in Portuguese)
for the first time in 1931, and has used it continuously since 1985
in the southern states (south and southeast regions and the states
of Goiás
and Mato Grosso do
Sul), and in Bahia until 2004.
Formerly, starting and ending dates were variable, but in 2008, a
decree (No. 6558 of 09/09/2008) established a permanent rule: DST
starts at 00:00 on the third Sunday in October and ends at 00:00h
on the third Sunday in February—unless the latter falls during

Colombia
From
February 1992 until March 1993, Colombia
suffered rolling blackouts of up to 10 hours a day
due to a particularly strong El Niño
season, which dried the reservoirs in hydroelectric plants in a
country deriving 70% of its energy output from hydroelectric
sources; consequently, the government decided to use DST to help
save electricity. The experiment failed to deliver the
intended results, possibly due to Colombia's low latitude, and the
DST experiment was discontinued.
