World Daylight Saving Time Tracker
Who's on daylight saving time right now, and when does it change next? This isn't a list we maintain by hand — every row below is calculated live from your browser's own timezone database, the same source your operating system uses. If a country changes its DST rules, this page updates itself automatically; nothing here can go stale.

How This Is Calculated
For each city, this page compares its UTC offset in mid-January to its offset in mid-July. If they're the same, that place doesn't observe daylight saving at all. If they differ, whichever offset is currently active tells you whether it's on daylight saving or standard time right now — and a day-by-day scan forward finds the exact date the offset next changes. Every one of these facts comes straight from the timezone database built into your browser (the IANA Time Zone Database), which is what makes this self-correcting: when a government changes its DST law, browser vendors update that database, and this page reflects it automatically.

Frequently Asked Questions
Why do some countries never observe daylight saving time?
Daylight saving mainly benefits places with a big swing in daylight hours between
summer and winter — a mid-to-high-latitude effect. Countries near the equator see
roughly the same day length year-round, so shifting clocks wouldn't gain them anything.
Some higher-latitude countries, like Japan, China, and India, simply choose not to
observe it even though the daylight swing exists there.
Do all daylight-saving countries change their clocks on the same date?
No — one of the biggest sources of timezone confusion. The US and Canada typically
shift in early March and early November; the EU and UK shift on the last Sunday of
March and October; other countries set their own dates entirely. Because these dates
don't line up, the hour gap between two DST-observing regions can briefly change for a
week or two each spring and autumn, even though it's fixed the rest of the year.
Which hemisphere "springs forward" in March versus September?
The Northern Hemisphere springs forward around March and falls back around October or
November. The Southern Hemisphere is on the opposite calendar, springing forward around
September/October and falling back around March or April — their summer lines up with
the Northern Hemisphere's winter.
How does this tracker stay accurate without being updated by hand?
Every row is calculated live from the IANA Time Zone Database built into your browser —
the same database operating systems, phones, and servers use. When a government changes
its daylight-saving law, browser vendors update that database, and this page reflects
the new rule the next time it loads. Nothing here is typed in by hand.
