World Clock
Live local time in as many cities as you want to watch, sorted west to east, with the offset from you spelled out.
No cities on the board. Search above to add one.
Your board is remembered on this device only. Nothing is sent anywhere.
A clock board you can actually read
Most world clocks show you a fixed list of capitals. This one starts with a sensible board and then gets out of your way: search for a city, press it, and it joins the row. Cards are ordered west to east, so the board reads like a strip of the globe rather than the order you happened to add them in. A card dims at night in that city, which is the fastest way to see whether calling now would be rude.
Under each time you get the date there, the offset from UTC, the zone's short name where it has a real one, and how far ahead or behind you it is. That last line is the one people actually want. Knowing Tokyo is UTC+09:00 is only useful once you have subtracted your own offset in your head, so the subtraction is done for you.
Daylight saving is never guessed
Every time on this page is produced by your browser's own copy of the IANA time zone database, the same database operating systems use. That matters more than it sounds. A page that stores its own table of offsets is wrong twice a year in every country that changes its clocks, and quietly wrong for years in countries that change the rules, as Mexico did in 2022 and as several others have since. Because nothing is stored here, a zone that shifts its rules is right the moment your browser updates.
Half-hour and quarter-hour zones
India is UTC+05:30, Nepal is UTC+05:45, parts of Australia are UTC+08:45, and the Chatham Islands run at UTC+12:45. The difference line handles these properly and will tell you that Kathmandu is 15 minutes ahead of Delhi rather than rounding it away. If you want the reasoning behind those odd offsets, the guide on half-hour and quarter-hour time zones explains where they come from.
What this is not
This is a board for watching, not for planning. If you are trying to find an hour that works for people in three countries, the time zone converter and meeting planner is the tool for that: it puts a 24-hour strip against each city and shades the hours everyone is awake. Use the world clock to check what time it is, and the planner to decide when something should happen.
Frequently asked questions
How many cities can I add?
As many as you like. The board is a simple grid, so it keeps working with two cities or twenty; on a phone the cards stack into a single column.
Does it remember my cities?
Yes, on that device only. The list is kept in your browser’s local storage, never on a server, so it survives a refresh but does not follow you to another computer and is not tied to any account.
Is the time exact?
It is as exact as your own device clock, because that is what it reads. If your computer clock is a minute fast, every card is a minute fast. The offsets and daylight saving rules come from your browser, which keeps them current.
Why is a card darker?
The card dims between 7pm and 6am local time in that city, so you can see at a glance who is probably asleep before you call.
Can I show a 24-hour clock?
Yes. The Preferences menu in the header switches the whole site between 12-hour and 24-hour time, and the world clock follows it immediately.
