The northern hemisphere dominates the list: the United States and Canada change on the second Sunday of March and the first Sunday of November, and Europe changes on the last Sunday of March and the last Sunday of October. The southern hemisphere is the mirror image: Australia and New Zealand move their clocks forward in October and back in April. The two hemispheres change in opposite directions, so the offset between a northern city and a southern city changes four times a year — twice for each hemisphere.
Two changes to watch in 2027
Vancouver does not change its clocks at all in 2027: British Columbia moved to permanent Pacific Time (UTC−7) in 2026, so there is no spring forward and no fall-back. Casablanca does not change either: Morocco abolished daylight saving in 2026 and stays on UTC+0 permanently. Both are cases where the rules changed and old calendars are wrong.
The rest of the world changes as usual: North America on the second Sunday of March and the first Sunday of November, Europe on the last Sunday of March and the last Sunday of October, and Australia and New Zealand in the opposite direction. The table above gives the exact dates for every zone.
Looking back at 2026
In 2026, 51 of the 100 time zones covered on this site observed daylight saving. The year was notable for two abolitions: British Columbia moved to permanent Pacific Time, so Vancouver had no fall-back in November 2026, and Morocco abolished daylight saving by decree in June 2026, with its last change on 20 September 2026. Both are cases where the rules changed and old calendars are wrong — and both are recorded in the IANA Time Zone Database, which is what this site's tools use.
What the change means in practice
The clock change is not just an hour on the clock. In spring, everyone loses an hour of sleep, and studies consistently find a spike in road accidents, heart attacks and workplace injuries in the days after the change. In autumn, the hour is regained, and there is no comparable spike. For travellers, the change means checking flight times: a flight that leaves at 2am on the night of the change may not exist, or may exist twice. For anyone scheduling across time zones, it means checking the offset for the date, not the offset you remember — the time zone converter applies the rules for the date you choose.
Frequently asked questions
When does daylight saving start in 2027?
It depends on the hemisphere: the northern hemisphere moves its clocks forward in March, and the southern hemisphere in October. The table above gives the exact dates for every zone.
When does daylight saving end in 2027?
The northern hemisphere moves its clocks back in October or November, and the southern hemisphere in April. The table above gives the exact dates for every zone.
How many time zones observe daylight saving in 2027?
49 of the 100 zones covered on this site — 43 in the northern hemisphere and 6 in the southern hemisphere.
Does every country observe daylight saving?
No. Most of Africa and Asia do not, and several countries have abolished it — Russia in 2014, Türkiye in 2016, Brazil in 2019, Mexico in 2022, Jordan in 2022, and Morocco in 2026.
How do I check the daylight saving dates for a city?
Use the time zone converter: enter the city and the date, and it shows the offset in effect on that date. The city's own page — for example the daylight saving page for New York — gives the dates too.
