World clock
The current time in major cities around the globe, with the difference from your local time. It refreshes on its own, every second.
🕒 Your local time is --:--:--
No city found: try a different name (for example "London" or "Dubai").
How the time difference is calculated
Each city is tied to its official time zone from the IANA database, the same one your computer and phone use, so the difference shown already accounts for daylight saving time. When the US "springs forward" but Europe hasn't yet, or vice versa, the gap shifts for a couple of weeks, and here you always see the up-to-date value. Some countries use half-hour offsets: India, for instance, runs 9 hours and 30 minutes ahead of New York during Eastern Daylight Time.
The best time to call across time zones
Rule of thumb from the US East Coast: for Europe (+5 to +6 hours) call in the morning, which is their afternoon; for Tokyo or Sydney (+13 to +14 hours) evening works best, since it's already the next morning there. The "tomorrow" or "yesterday" badge next to a city warns you that the calendar there shows a different date than yours, handy for scheduling meetings and hitting deadlines without slipping a day.
