Where does this data come from?

The IANA Time Zone Database. Each transition is computed on our server, when the page is generated, by scanning the offset rules in the server's tzdata, so it reflects changes such as Iran's 2022 and Mexico's 2022 abolition of DST and Egypt's 2023 reinstatement. Governments can still change their rules at short notice.

How precise are the transition times?

The date and local time of each change are exact. We scan day by day to find the day the offset changes, then narrow the moment down to within a minute; clock changes happen on the hour (or half hour) in practice, so that is enough to show the local time correctly.

Why do some countries show no transitions?

They've abolished DST or never observed it. Japan, India, China, and most of the equatorial world have had a constant year-round offset for decades. The page lists them explicitly so you know the absence isn't a bug.

Does the EU still plan to abolish DST?

In March 2019 the European Parliament adopted its position on a Commission proposal to end the twice-yearly clock change, but the proposal has stalled in the Council of the EU, where member states have not agreed a common approach. Until a law is adopted and the IANA database is updated, EU countries keep changing their clocks on the last Sundays of March and October.

DST calendar

When does daylight saving change?

The next clock change for 18 countries and regions, with the local date, which way the clocks move, and the UTC offset before and after.

Computed from the IANA time zone rules on 5 November 2026.

Reading the list

How to read the clock-change list

Each card shows whether the place itself changes its clocks soon, or keeps the same offset all year.

Which way the clocks move

"Clocks go forward" means daylight saving time starts and the UTC offset grows by an hour; "clocks go back" means it ends. The southern hemisphere does this in the opposite months to the north, so Sydney and Auckland end DST in April while Europe and North America start it in March.

When changes cluster

The next changes listed here fall mostly in March (6), April (4). Because North America, Europe and the southern hemisphere change on different weekends, the hour gap between them shifts for a few weeks each spring and autumn.

Countries without clock changes

8 of the places listed have no clock change scheduled before the end of next year, including Australia (Perth — no DST), Brazil (São Paulo — no DST since 2019), Mexico (Mexico City — no DST since 2022), Iran (no DST since 2022), Japan (no DST), India (no DST). Their gap to DST-observing countries still changes when those countries move their clocks.

Rules can change

These dates follow the IANA time zone rules in use when the page was generated. Governments sometimes change daylight saving rules at short notice; the official announcement in each country is the final authority.
