Israel Summer Time (Hebrew : שעון קיץsha'on kayits "Summer Clock"), also in English, Israel Daylight Time (IDT) is the practice in Israel by which clocks are advanced by one hour, beginning on the Friday before the last Sunday of March, and ending on the last Sunday of October.
Before 1992, daylight saving was governed by the Time Act , a law inherited by Israel from the British Mandate of Palestine, which started to use daylight saving in World War II. [1] Summer Time was introduced in Israel between the years 1948–1957, but the length of Daylight Saving Time has changed significantly depending on the year. In 1951–1952, it was enacted for about seven months, whereas in the years 1953–1954 it was enacted for only three months. In 1958, daylight saving time was canceled. Due to the global energy crisis because of the aftermath of the Yom Kippur War, Summer Time was enacted again from 1974–1975.
Up until 1992, daylight saving time was operated by an order of the minister of the interior. In 1980 the authority of the minister for this matter was contested in an appeal to the supreme court. The supreme court decided that the minister's authority was indeed more limited than the common practice, as he may only decide on the dates of IDT while its operation is unquestionable. Following this decision the Knesset amended the Time Act so the minister will also have the authority to abolish IDT in a certain year.
The Law Determining the Time (Hebrew : חוק קביעת הזמןHok Kvi'at Hazman) is an Israel law governing Israeli daylight saving time. It was approved by the Knesset in 1992, replacing the British Mandate of Palestine time act inherited by Israel. The 1992 time zone law cancelled the Time Act, and stipulated that IDT will be operated for at least 150 days each year, and that the final dates will be decided by the minister of the Interior, subject to the approval of the Knesset committee for internal affairs. In some years the decision as to which day summer time would start or end was made at the last minute due to political haggling and this caused disruption to international airline schedules at Ben Gurion Airport.[ citation needed ] An extreme demonstration of the uncertainty around IDT was in 1999 when two Palestinian car bombs exploded one hour too early, killing only the bombers themselves. [2]
This schedule was variable: the only requirement was that there be at least 150 days per year of IDT, and the dates were set out each year by the Ministry of the Interior. [3] [ dubious ]
Until 2005, the start and end of IDT each year was established in an ad hoc fashion as the result of haggling between political parties representing various sectors of Israeli society. Parties representing religious groups wanted the start delayed till after Passover and the end to precede Yom Kippur, the Day of Atonement, while the secular parties would argue for starting it earlier and ending it later. Thus, there was no established rule that could guarantee a predictable changeover in either direction. The debates about a fixed rule for determining the dates of IDT went on for years, and resulted in a suggestion that IDT will start on the 2nd day of Passover and end on the weekend between Rosh Hashanah and Yom Kippur. This suggestion was rejected as it stipulated an annual IDT period of only 5 months, and yet it served as the basis of the final compromise. After 2005, the annual debate has been effectively ended.
In the past, the unpredictability of IDT in Israel became frustrating enough that Microsoft Windows stopped trying to track changes and just made Israeli time be Greenwich Mean Time plus two hours (GMT+2) (and disabled the daylight saving option). This has led to various ad hoc solutions to the problem in Windows systems and other Microsoft software (e.g. Outlook calendar entries are often off by an hour when shared, due to the lack of IDT support). On November 17, 2009, Microsoft released an update that has daylight saving time enabled for Israel. However, the date for transition back to Standard Time is set as the Second Sunday of September, regardless of the Hebrew Calendar date. [4] Windows 7 does contain correct IDT times up to 2023, but not all software makes use of this extra information.
In 2010, due to an unusually large difference between the lunar based Hebrew calendar and the solar calendar the date of the return to winter time was September 12, which was very early. This sparked protests by the more secular public, and calls for a change in the way the date is determined. Many members of the government were sympathetic to this and at one point in the ensuing row the Minister even proposed moving to winter time just for Yom Kippur, the Day of Atonement and then returning to summer time. In September 2010 the argument over the dates for summer time reached new heights and some firms even refused to adopt it. [5] [6]
On 6 June 2011, Internal Affairs Minister Eli Yishai announced his support for extending IDT, setting the ending time to the beginning of October. The change required the approval of the Knesset. [7]
On November 5, 2012, the Knesset approved the bill to extend IDT to a period of 193 days, beginning on the Friday before the last Sunday in March (at 2:00 local time, or 0:00 UTC, clocks are moved forward by one hour), and ending on the first Sunday after October 1 (at 2:00 IDT or 23:00 UTC Saturday, clocks are moved back by one hour).
If the end of IDT falls on Rosh Hashana, then IDT will end on the first Monday after October 1. [8]
On July 8, 2013, the Knesset approved the bill to extend IDT even further. According to the bill, IDT will begin on the Friday before the last Sunday of March, and end on the last Sunday of October. [9]
In March 2020, the Israeli government planned to delay daylight saving in order to discourage gatherings during coronavirus. However, it was decided this would be too technically difficult to implement at such short notice. [10]

The Hebrew calendar, also called Jewish calendar, is a lunisolar calendar used today predominantly for Jewish religious observances. It determines the dates for Jewish holidays and the appropriate public reading of Torah portions, yahrzeits, and daily Psalm readings, among many ceremonial uses. In Israel, it is used for religious purposes, provides a time frame for agriculture and is an official calendar for civil purposes, although the latter usage has been steadily declining in favor of the Gregorian calendar.
Jewish holidays, also known as Jewish festivals or Yamim Tovim, are holidays observed in Judaism and by Jews throughout the Hebrew calendar. They include religious, cultural and national elements, derived from three sources: biblical mitzvot ("commandments"); rabbinic mandates; Jewish history and the history of the State of Israel.
A time zone is a designated area of the globe that observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions instead of strictly following longitude because it is convenient for areas in close commercial or other communication to keep the same time. France, including its overseas territories, has the most time zones of any country, with a total of 12.
Yom Kippur, also known as the Day of Atonement, is the holiest day of the year in Judaism. Its central themes are atonement and repentance. Jews traditionally observe this holy day with a day-long fast and intensive prayer, often spending most of the day in synagogue services.
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.
Yom Hazikaron laShoah ve-laG'vurah, known colloquially in Israel and abroad as Yom HaShoah and in English as Holocaust Remembrance Day, or Holocaust Day, is observed as Israel's day of commemoration for the approximately six million Jews who perished in the Holocaust as a result of the actions carried out by Nazi Germany and its collaborators, and for the Jewish resistance in that period. In Israel, it is a national memorial day. The first official commemorations took place in 1951, and the observance of the day was anchored in a law passed by the Knesset in 1959. It is held on the 27th of Nisan, unless the 27th would be adjacent to the Jewish Sabbath, in which case the date is shifted by a day.
Independence Day is the national day of Israel, commemorating the Israeli Declaration of Independence in 1948. The day is marked by official and unofficial ceremonies and observances.
Yom HaZikaron, in full Yom HaZikaron LeHalalei Ma'arakhot Yisrael ul'Nifge'ei Pe'ulot HaEivah, is Israel's official remembrance day, enacted into law in 1963. While Yom HaZikaron has been traditionally dedicated to fallen soldiers, commemoration has also been extended to civilian victims of terrorism.

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