Why the New York – London gap changes
The US and the UK change their clocks on different dates. In spring 2027 the US moves forward on March 14 and the UK on March 28, so for two weeks New York is only 4 hours behind London instead of 5. The same thing happens in autumn: in 2026 the UK went back on October 25 and the US on November 1. Recurring meetings across the Atlantic move by an hour for one side during those weeks.

Frequently asked questions
How many cities can I add?
As many as you like. Your list is saved in this browser. Cities follow the official time zone names, so India appears as Kolkata and Vietnam as Ho Chi Minh.
Does the world clock handle daylight saving time?
Yes. Offsets come from the time zone database built into your browser, so clock changes appear automatically.
What time is it in Manila when it is 9 AM in New York?
In November it is 10 PM the same day in Manila (13 hours ahead). From mid-March to early November, when New York is on daylight time, the gap is 12 hours.
Why does India have a half-hour offset?
India uses one national time, IST, set at UTC+5:30, close to the solar time in the middle of the country. A few other places, such as Nepal (+5:45), use 15- or 30-minute offsets too.
