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]

Contents

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−03:00, 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. [7]

In 1903, another official time was operating in Coquimbo. It was synchronized at -4 hours, 45 minutes 20.7 seconds with respect to GMT. [7]

On January 10, 1910, Chile adopted GMT-5 as its official time. [7]

On July 1, 1919, time was set as 4 hours 42 minutes 46.3 seconds behind Greenwich. [7]

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 20:00 on a Saturday. [7] 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:

Daylight saving time Time adjustment practice

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

Western European Summer 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:

Japan Standard Time

Japan Standard Time, abbreviated as JST, is the standard time zone in Japan, 9 hours ahead of UTC. There is no daylight saving time, though its introduction has been debated several times. During World War II, it was often called Tokyo Standard Time.

Central Time Zone Time zone in North America

The North American Central Time Zone (CT) is a time zone in parts of Canada, the United States, Mexico, Central America, some Caribbean Islands, and part of the Eastern Pacific Ocean.

Time in the United States Timekeeping in the USA

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

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

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).

Atlantic Time Zone 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. 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.

UTC−03:00 Identifier for a time offset from UTC of −3

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

UTC−04:00 Identifier for a time offset from UTC of −4

UTC−04:00 is an identifier for a time offset from UTC of −04:00. It is observed in the Eastern Time Zone during the warm months of daylight saving time, as Eastern Daylight Time. The Atlantic Time Zone observes it during standard time . It is observed all year in the Eastern Caribbean.

UTC+03:00

UTC+03:00 is an identifier for a time offset from UTC of +03:00. In areas using this time offset, the time is three hours later than the Coordinated Universal Time (UTC). Following the ISO 8601 standard, a time with this offset would be written as, for example, 2019-02-08T23:36:06+03:00.

Time in Australia Time zones in Australia

Australia uses three main time zones: Australian Western Standard Time, Australian Central Standard Time, and Australian Eastern Standard Time. Time is regulated by the individual state governments, some of which observe daylight saving time (DST). Australia's external territories observe different time zones.

Time in Russia About the 11 time zones of Russia

There are eleven time zones in Russia, which currently observe times ranging from UTC+02:00 to UTC+12:00. Daylight saving time is not used in Russia. From 27 March 2011 to 26 October 2014, permanent DST was used.

The UTC offset is the difference in hours and minutes from Coordinated Universal Time (UTC) for a particular place and date. It is generally shown in the format ±[hh]:[mm], ±[hh][mm], or ±[hh]. So if the time being described is one hour ahead of UTC, the UTC offset would be "+01:00", "+0100", or simply "+01".

Time in Mexico Overview about the time zones in Mexico

Mexico uses four main time zones since February 2015. Most of the country observes Daylight Saving Time.

  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.
  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 the U.S. state of Arizona, does not observe daylight saving time.
  4. Zona Noroeste covers the state of Baja California. It is identical to U.S. Pacific Time, including the daylight saving time 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 of America participating, but much less so in South America.

Daylight saving time in Asia

As of 2017, daylight saving time is used in the following Asian countries:

Time 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

Most areas in Europe and North America observe daylight saving time (DST), whereas most areas of Africa and Asia do not. In South America, most countries in the north of the continent near the Equator do not observe DST, whereas Paraguay and most of Chile do. The practice of observing daylight saving time in Oceania is also mixed, with New Zealand and parts of southeastern Australia observing DST, while most other areas do not.

Winter time (clock lag)

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.
