A world clock built for moving around

When you travel or work across time zones, the question is rarely just “what time is it there?” It is “are they awake, is it a working day, and will the gap change next week?” Each clock here shows the local date (handy across the International Date Line), the offset from wherever your device currently is, working hours, and the next daylight saving change, because the gap between London and New York shrinks to four hours for a few weeks each spring and autumn when their changes don’t line up.

Converting a specific time? Use the time zone converter. Scheduling a call for several people? Try the meeting planner. Or look up the current time in a city.

Frequently asked questions

How does this world clock work?

It reads your device’s clock and converts it into each city’s local time using the IANA time zone database built into your browser, which includes every daylight saving rule. Your city list is saved on this device only.

Does it adjust for daylight saving time automatically?

Yes. Each clock shows its current UTC offset and abbreviation, and the next daylight saving change if the zone observes one.

How many time zones are there?

There are 38 or so distinct local offsets in use, ranging from UTC−12 to UTC+14, including half-hour offsets such as India (UTC+5:30) and quarter-hour ones such as Nepal (UTC+5:45). The IANA database tracks over 400 named zones because regions have changed their rules at different times.

Can I see when it is a good time to call?

Yes. Each clock is shaded for day and night, and working hours (09:00–18:00) are marked. For picking a slot that suits everyone, use the meeting planner.
