Many countries around the world observe Daylight Saving Time (DST), also known as Summer Time, during their summer. This transfers one hour of morning daylight to the evening. To accomplish this the clocks are set ahead one hour in the spring and turned back one hour in the fall.
For more details, visit the Daylight Saving Time page at Wikipedia.
The DST rules have been researched for the years starting around the year 2000 to the present. For some regions, we have a Time Zone setting that can handle locations that have used different time offsets and/or multiple DST rules. The future dates of these observances are set by the government of the country or locality and are subject to change. Also see FAQs and DST adjustments.
Calendars created for all future years to 2099 will use the DST rules in this table. The Time Zone setting (which can handle time offset changes) uses these rules to calculate DST transition dates, and has precedence over applying DST rules to a location as some locations use two (e.g. Bahamas.)

Footnotes:
Saskatchewan, Canada does not observe DST. Since 2026, neither do British Columbia (permanently -7:00 from 8 March), Alberta (permanently -6:00 from 18 June), nor the Northwest Territories (permanently -6:00 from 21 August).
For some provinces, including Saskatchewan, there are smaller geographic areas within them that set their own rules, see Time in Canada at Wikipedia.
Iran starts DST on the first day of Farvardin in the Iranian calendar and ends on the last day of Shahrivar. The dates used on this site are approximate. See Iran Daylight Saving time at Wikipedia.
Currently, Israeli law defines the end of DST to start on the Friday before the last Sunday in March and end on the last Sunday in October. See Israel Daylight Saving time at Wikipedia.
The state of Baja California and some Mexican cities that border the United States follow the North America (USA) DST rules.
The state of Sonora does not observe DST.
Some locations observed War time, Peace time, or DST during World War II. Research local information and adjust times accordingly.
In the United States, Arizona and Hawaii do not observe DST. Some cities in Arizona, such as Chinle, Kayenta and Monument Valley Navajo Tribal Park in the Navajo Nation do observe DST. Indiana currently observes DST, but this has varied over previous years, see Time in Indiana at Wikipedia.
In July 2014, Russia voted to stop observing DST effective that year and to make Standard (Winter) Time permanent. Russia stopped observing DST on Sunday, October 26, 2014. For the year 2015 and all future years, Russia will stay on Standard (Winter) Time all year long. See Time in Russia at Wikipedia.
For the year 2011, Turkey moved the start of DST to Monday, March 28, one day later than the rest of Europe.
For the year 2014, Turkey switched to European Summer Time on Monday, March 31.
In 2016, Turkey cancelled DST observance and decided to stay on Summer Time (+1 hour to the base time zone) all year. This effectively means the country observes permanent UTC+3, instead of the existing UTC+2.
In Australia, the states of Queensland, Western Australia, and the Northern Territory do not observe DST. For Lord Howe Island, use the Australia/Lord_Howe time zone setting which handles the DST time offset of 30 minutes.
On 5 September 2010 the Falkland Islands stopped observing DST and have stayed on -3:00 all year since. Outside of Stanley and the RAF Mount Pleasant, Camp Time is used which does not observe DST.
Palestine schedules DST around Ramadan, so it does not always follow a fixed rule. From 2023 to 2025 DST started late, in April (29 April 2023, 20 April 2024, and 12 April 2025) rather than in March.
From 2036 through 2086 it is the end date that moves earlier each year — for example DST ends 18 October 2036, 10 October 2037, 25 September 2038, and 17 September 2039. In many of those years DST is also suspended for Ramadan and then resumed, giving four time changes in the year instead of two. From 2087 the simple fourth-Saturday-in-March to last-Saturday-in-October rule applies again.
