Daylight Saving Time Around the World: Who Changes Their Clocks?
Roughly a third of the world's countries use daylight saving, and the dates differ by region.
Who uses it
The UK, the EU, the United States, Canada, most of Mexico until 2022, parts of Australia, New Zealand, Chile and Paraguay (until recently) use some form of seasonal clock change. The UK and EU change on the last Sundays of March and October. The US changes on the second Sunday of March and the first Sunday of November.
Who has stopped, and who never started
Russia, Turkey, Brazil, Mexico and Iran have ended seasonal changes in recent years. Most countries near the equator, including Singapore, Kenya and Nigeria, never needed it, because day length hardly changes through the year.
Because countries change on different dates, time gaps between them shift by an hour at certain weeks of the year, which is why our converter pages list every date the gap changes.
Frequently asked questions
Do all European countries change their clocks together?
EU countries do. Some others, such as Iceland, Russia, Belarus and Turkey, do not change clocks at all.
