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 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.

Current time zone

The official time on the mainland is now UTC−04:00, in the Magallanes and Chilean Antarctica Region is UTC−03:00, and on Easter Island is UTC−06:00.

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:

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.

Western European Summer Time is a summer daylight saving time scheme, 1 hour ahead of Greenwich Mean Time and Coordinated Universal Time. It is used in:

<span class="mw-page-title-main">Japan Standard Time</span> Standard Time Zone in Japan

Japan Standard Time, or Japan Central Standard Time, is the standard time zone in Japan, 9 hours ahead of UTC. Japan does not observe daylight saving time, though its introduction has been debated on several occasions. During World War II, the time zone was often referred to as Tokyo Standard Time.

<span class="mw-page-title-main">Time in the United States</span> U.S. time zones

Time in the United States, by law, is divided into nine standard time zones covering the states, territories and other US possessions, with most of the United States observing daylight saving time (DST) for approximately the spring, summer, and fall months. The time zone boundaries and DST observance are regulated by the Department of Transportation. Official and highly precise timekeeping services (clocks) are provided by two federal agencies: the National Institute of Standards and Technology (NIST) ; and the United States Naval Observatory (USNO). The clocks run by these services are kept synchronized with each other as well as with those of other international timekeeping organizations.

Summer time in Europe Variation of standard clock time

Summer time in Europe is the variation of standard clock time that is applied in most European countries in the period between spring and autumn, during which clocks are advanced by one hour from the time observed in the rest of the year, with a view to making the most efficient use of seasonal daylight. It corresponds to the notion and practice of daylight saving time (DST) to be found in many other parts of the world.

Time in New Zealand is divided by law into two standard time zones. The main islands use New Zealand Standard Time (NZST), 12 hours in advance of Coordinated Universal Time (UTC) / military M (Mike), while the outlying Chatham Islands use Chatham Standard Time (CHAST), 12 hours 45 minutes in advance of UTC / military M^ (Mike-Three).

<span class="mw-page-title-main">Atlantic Time Zone</span> Time zone (UTC−04:00)

The Atlantic Time Zone is a geographical region that keeps standard time—called Atlantic Standard Time (AST)—by subtracting four hours from Coordinated Universal Time (UTC), resulting in UTC−04:00. AST is observed in parts of North America and some Caribbean islands. During part of the year, some portions of the zone observe daylight saving time, referred to as Atlantic Daylight Time (ADT), by moving their clocks forward one hour to result in UTC−03:00. The clock time in this zone is based on the mean solar time of the 60th meridian west of the Greenwich Observatory.

Moscow Time Time zone in western Russia (UTC+3)

Moscow Time is the time zone for the city of Moscow, Russia, and most of western Russia, including Saint Petersburg. It is the second-westernmost of the eleven time zones of Russia. It has been set to UTC+03:00 without DST since 26 October 2014; before that date it had been set to UTC+04:00 year-round on 27 March 2011.

<span class="mw-page-title-main">UTC+03:00</span> Identifier for a time offset from UTC of +3

Mexico uses four main time zones as of February 2015. Most of the country observes Daylight Saving Time (DST).

  1. Zona Sureste covers the state of Quintana Roo is UTC−05:00 year round. It is the equivalent of U.S. Eastern Standard Time.
  2. Zona Centro covers the eastern three-fourths of Mexico, including Mexico City, Guadalajara, and Monterrey. For most of the year, it is the equivalent of U.S. Central Time and observes DST.
  3. Zona Pacífico covers the states of Baja California Sur, Chihuahua, Nayarit, Sinaloa, and Sonora. For most of the year, it is the equivalent of U.S. Mountain Time. The state of Sonora, like most of the adjacent U.S. state of Arizona, does not observe DST.
  4. Zona Noroeste covers the state of Baja California. It is identical to U.S. Pacific Time, including the DST schedule.

Daylight saving time in the Americas is the arrangement in the Americas by which clocks are advanced by one hour in spring and moved back in autumn, to make the most of seasonal daylight. The practice is widespread in North America, with most of Canada, Mexico, and the United States participating, but much less so in South America.

Daylight saving time in Morocco

As of 2018, daylight saving time (DST) is permanently observed in Morocco. Previously, time was advanced to UTC+01:00 at 02:00 on the last Sunday of March, and reverted to UTC±00:00, defined as Greenwich Mean Time locally, at 03:00 on the last Sunday of October. This practice was continued through October 2018, after which clocks were permanently advanced. An exception was made during the month of Ramadan during which clocks reverted to UTC+00:00.

<span class="mw-page-title-main">Time in Portugal</span> Time zones in Portugal

Portugal has two time zones and observes daylight saving time. Continental Portugal and Madeira use UTC+00:00, while the Azores use UTC–01:00. Daylight saving time is observed nationwide from the last Sunday in March to the last Sunday in October, so that every year, continental Portugal and Madeira temporarily use UTC+01:00, and the Azores temporarily use UTC+00:00.

Daylight saving time by country

Daylight saving time (DST), also known as summer time, is the practice of advancing clocks during part of the year, typically by one hour around spring and summer, so that daylight ends at a later time of the day. As of 2022, DST is observed in most of Europe, most of North America and parts of Asia around the Northern Hemisphere summer, and in parts of South America and Oceania around the Southern Hemisphere summer. It was also formerly observed in other areas.

Time in Spain Time zones in Spain

Spain has two time zones and observes daylight saving time. Spain mainly uses Central European Time (GMT+01:00) and Central European Summer Time (GMT+02:00) in Peninsular Spain, the Balearic Islands, Ceuta, Melilla and plazas de soberanía. In the Canary Islands, the time zone is Western European Time (GMT±00:00) and Western European Summer Time (GMT+01:00). Daylight saving time is observed from the last Sunday in March to the last Sunday in October throughout Spain.

Winter time (clock lag) Aspect of daylight saving time

Winter time is the practice of shifting the clock back during winter months, usually −1 hour. It is a form of daylight saving time which is the opposite compensation to the summer time. However, while summer time is widely applied, use of winter time has been and is very rare.
