The three time zones of Chile since 2017.

Time in Chile is divided into three time zones. Most of Continental Chile uses the time offset UTC−04:00 in winter time and UTC−03:00 in summer time, while the Magallanes and Chilean Antarctica region uses the time offset UTC-03:00 the whole year. Additionally, Easter Island uses the time offset UTC−06:00 in winter time and UTC−05:00 in summer time.[1]

Until 2015, Continental Chile used the time offset UTC−04:00 and Easter Island used UTC−06:00 for standard time, with daylight saving time roughly between October and March every year. In January 2015, the Chilean government announced that the entire country would keep the time offset used during daylight saving time permanently.[2][3] However, the annual time change was reinstated in 2016 after feedback from the public about an increase in truancy during the winter months,[4] complaints about older computers and other electronic devices not using the right time zone, and fruit growers reporting a 15% loss in productivity.[5]

Starting in 2016, Chile returned to UTC−04:00 for winter time for 3 months. Between 2016 and 2018, this began on the second Sunday of May and ended on the second Sunday of August;[6] from 2019 onward, it will start on the first Sunday of April and end on the first Sunday of September. Since 2017, a new time zone in the Magallanes and Chilean Antarctica region has been implemented, giving two different times in Continental Chile for the first time.

Time zone

Time zone

A time zone is an area which observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time.

Continental Chile

Continental Chile

Continental Chile is the name given to the Chilean territory located on the continental shelf of South America. This term serves to distinguish the South American area from the insular territories, known as Insular Chile, as from the Antarctic Chile. The existence of this three areas of effective or claimed Chilean sovereignty is what supports the existing tricontinental principle in this country.

UTC offset

UTC offset

The UTC offset is the difference in hours and minutes between Coordinated Universal Time (UTC) and local solar time, at a particular place. This difference is expressed with respect to UTC and is generally shown in the format ±[hh]:[mm], ±[hh][mm], or ±[hh]. So if the time being described is two hours ahead of UTC, the UTC offset would be "+02:00", "+0200", or simply "+02".

UTC−04:00

UTC−04:00

UTC−04:00 is an identifier for a time offset from UTC of −04:00.

UTC−03:00

UTC−03:00

UTC−03:00 is an identifier for a time offset from UTC of −03:00.

Easter Island

Easter Island

Easter Island is an island and special territory of Chile in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian Triangle in Oceania. The island is most famous for its nearly 1,000 extant monumental statues, called moai, which were created by the early Rapa Nui people. In 1995, UNESCO named Easter Island a World Heritage Site, with much of the island protected within Rapa Nui National Park.

UTC−06:00

UTC−06:00

UTC−06:00 is an identifier for a time offset from UTC of −06:00. In North America, it is observed in the Central Time Zone during standard time, and in the Mountain Time Zone during the other eight months. Several Latin American countries and a few other places use it year-round.

UTC−05:00

UTC−05:00

UTC−05:00 is an identifier for a time offset from UTC of −05:00. In North America, it is observed in the Eastern Time Zone during standard time, and in the Central Time Zone during the other eight months. The western Caribbean uses it year round.

Daylight saving time

Daylight saving time

Daylight saving time (DST), also referred to as daylight savings time, daylight time, or summer time, is the practice of advancing clocks during warmer months so that darkness falls at a later clock time. The typical implementation of DST is to set clocks forward by one hour in either the late winter or spring, and to set clocks back by one hour in the fall to return to standard time. As a result, there is one 23-hour day in early spring and one 25-hour day in the middle of autumn.

Chile

Chile

Chile, officially the Republic of Chile, is a country located in western South America. It is the southernmost country in the world and closest to Antarctica, stretching along a narrow strip of land between the Andes Mountains and the Pacific Ocean. With an area of 756,096 square kilometers (291,930 sq mi) and a population of 17.5 million as of 2017, Chile shares borders with Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage to the south. The country also controls several Pacific islands, including Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island, and claims about 1,250,000 square kilometers (480,000 sq mi) of Antarctica as the Chilean Antarctic Territory. The capital and largest city of Chile is Santiago, and the national language is Spanish.

Time zones

The winter time starts the first Saturday of April and ends on the first Saturday of September.

It has 2 hours of difference from the Continental time and changes the same days.

Defunct time zones

Standard time (CLT/EAST)

Standard time in Chile was used in Chile until 2014 (returned 2016). The time zone Chile Standard Time (CLT) was used on the mainland with the offset UTC−04:00 and Easter Island Standard Time (EAST) was used on Easter Island with the offset UTC−06:00.

On March 1, 1894, the first official time signal operates in Valparaiso at -4 hours, 46 minutes and 34 seconds with respect to GMT, as UTC did not exist.[8]

In 1903, another official time was operating in Coquimbo. It was synchronized at -4 hours, 45 minutes 20.7 seconds with respect to GMT.[8]

On January 10, 1910, Chile adopted GMT-5 as its official time.[8]

On July 1, 1919, time was set as 4 hours 42 minutes 46.3 seconds behind Greenwich.[8]

Summer time (CLST/EASST)

Summer time in Chile, also known as daylight saving time (DST) in Chile was used in Chile from 1968 to 2014 & 2016–present. The time zone Chile Summer Time (CLST) was used on the mainland with the offset UTC−03:00 and Easter Island Summer Time (EASST) was used on Easter Island with the offset UTC−05:00. In mainland Chile, time was changed at 24:00 on a Saturday, i.e. at 0:00 on the following Sunday. In Easter Island, time was changed at 22:00 on a Saturday.[8] In 2015, the time offset used in this time zone eventually became the only time zone in Chile.

Several exceptions have been decreed to the current rule that began in 1968:

  • In 1987, the daylight saving time was extended until Saturday 11 April to accommodate a visit by Pope John Paul II[8]
  • In 1988, daylight saving time began a week early, to have more light for the Chilean national plebiscite of 5 October[9]
  • In 1990, daylight saving time was extended to 17 March, because Patricio Aylwin began his presidential period on 11 March[9]
  • In 1990, daylight saving time began at the end of 15 September, in order to save electricity due to unfavorable hydrological conditions[9]
  • In 1997, standard time began at the end of 29 March, in order to cope with unfavorable hydrological conditions[10]
  • In 1999, daylight saving time was extended to the first Saturday of April, due to a severe drought[8]
  • In 2008, daylight saving time was extended 3 weeks, due to a severe drought[8]
  • Due to the 2010 Chile earthquake, daylight saving time ended at 0:00 of 4 April on Continental Chile (20:00 Saturday 3rd on Easter Island)[11]
  • In 2011, the government decided to end daylight saving on the first Saturday of April. Later this was postponed to the first Saturday of May.[12]
  • On February 15, 2013, DST was extended to the last Sunday of April and started DST on the 2nd Sunday of September. These dates would be nearly the exact dates of North America's DST, reversed to the southern hemisphere, but the DST end date is 1 week early.[13]
  • In 2015, the summer time was implemented the whole year.
  • In 2016, the change to winter time was restored.
  • In 2017, the Magallanes and Chilean Antarctica region began to have its own time zone, using summer time (UTC−3) the whole year.
