Upcoming Daylight Saving Time Changes

These are the two dates that matter most for the March 2027 spring-forward season in the northern hemisphere. The US and Canada move first, and Europe and the UK follow.

The US–Europe overlap weeks (14 March 2027 – 28 March 2027)

Most of the US and Canada are already on daylight time while Europe and the UK are still on standard time. Transatlantic gaps shrink by one hour for those weeks, then return after Europe springs forward. A recurring transatlantic meeting that was booked for 10:00 in London may land at a different local hour in New York for those weeks unless you replan it.

Gap column shows the absolute time difference on the sample dates before the US springs forward, during the overlap weeks, and after Europe springs forward.

Use the homepage meeting planner to compare working hours across cities and pick a time that still works after the clock change.

Regions that skip the northern spring-forward

Many meeting-time questions come from places that stay on one offset all year. These regions do not observe the March spring-forward in the northern hemisphere:

• India
• China
• Japan
• Singapore
• South Korea
• Brazil (most regions)
• Mexico (most regions)
• Arizona & Hawaii (US)
• Most of Africa

How daylight saving time changes work

Daylight saving time (DST) shifts local clocks seasonally, but countries do not all change on the same date. The calendar below uses each location's local transition time so you can see exactly when its UTC offset changes.
