World Clock
Live world clock — current time in multiple cities at once with dates, UTC offsets, 12/24-hour formats and your own city list. Free, no signup.
About the World Clock
This world clock shows the live current time in as many cities as you need, side by side, updating every second. Your own time zone is detected automatically and pinned as the first card; add up to twelve cities from a list of major hubs across the Americas, Europe, Africa, Asia and Oceania, and remove any with one click.
Every card shows the city's time, day of the week, date and UTC offset — so you immediately see not just the hour but whether it's already tomorrow (or still yesterday) there. Daylight saving is always correct because the display is driven by each city's real IANA time zone rules, not fixed offsets. Toggle 12-hour or 24-hour format and seconds on or off to match how you read time.
It's the dashboard to keep open when you work with remote teammates, follow markets that open across the globe, or time calls with family abroad. One click copies all the displayed times as text for pasting into a message.

Frequently Asked Questions
Does the world clock handle daylight saving time correctly?
Yes — each clock is rendered using the city's real IANA time zone database rules, the same source operating systems use. When New York switches to EDT or London to BST, the display follows automatically on the correct date, including the weeks when the usual offset between them temporarily changes.
What does the UTC offset on each card mean?
It's the city's current difference from Coordinated Universal Time — UTC+05:00 for Karachi, for example. Comparing two cities' offsets gives their mutual difference: Karachi at UTC+5 and New York at UTC-4 are nine hours apart. The offset shown always reflects DST when active.
My city isn't in the list — how do I show its time?
Add any listed city in the same time zone; the time will be identical. For example, Berlin covers all of Central Europe, Karachi covers Pakistan, Dubai covers the Gulf, and Los Angeles covers the US Pacific coast. Your own detected zone is always shown regardless of the list.
How accurate are the clocks?
As accurate as your device's clock, since the display derives every city's time from it — the page refreshes each second. If your computer syncs time over the internet (all modern systems do by default), the readings are effectively exact.
Why do some cities show a different date?
Because it genuinely is a different calendar day there. When it's Friday evening in New York it's already Saturday morning in Tokyo. Each card shows its own weekday and date precisely so you never schedule a 'tomorrow' that's actually 'today' for the other person.
