World Clock
A fixed UTC clock plus up to 5 customizable locations, updating live.
About the World Clock
This widget keeps a fixed UTC (Coordinated Universal Time) clock always visible alongside up to 5 locations you choose yourself — useful for coordinating meetings, deployments, or calls across timezones. UTC never shifts for daylight saving, which makes it a stable reference point: when a location's local clock shows a different offset in summer versus winter, it's that location's daylight saving rule changing, not UTC. Each location card's time and UTC offset are computed live from your browser's IANA timezone database (the same source system clocks use), so results automatically reflect the correct daylight saving behavior for that specific city on that specific date.
To use it: pick a city from the dropdown and click Add — up to 5 at once — and every clock ticks forward live, once a second. Remove any location with its card's Remove button. Your selections are saved to this browser's local storage, so they persist between visits on this device, though they won't follow you to a different browser or computer since nothing is synced to a server.
How many locations can I add?+−
Up to 5, on top of the fixed UTC clock. Your selection is saved in your browser so it's there next time you visit.
Does this account for daylight saving time?+−
Yes — offsets and times are computed live from your browser's timezone database, so they automatically reflect daylight saving changes.
Why is UTC always shown, separately from the locations I add?+−
UTC (Coordinated Universal Time) never observes daylight saving and is the reference every other timezone offset is defined against, which makes it a stable anchor point for coordinating across regions that may currently be on different daylight/standard schedules.
Where is my location list saved?+−
In your browser's local storage on this device only — it isn't sent to a server or synced across devices, so switching browsers or devices starts with the default set again.
Why do two cities in the same country sometimes show different times?+−
Large countries can span multiple timezones (the US spans six, for example), so which specific city you pick — not just the country — determines the offset and any daylight saving behavior shown.
What does the UTC offset shown for each location mean?+−
It's the current difference between that location's local time and UTC, such as UTC-5 or UTC+9 — this number itself can shift by an hour during the year in regions that observe daylight saving.
Can I remove the fixed UTC clock?+−
No — UTC stays pinned at the top as a constant reference point. You can remove any of your added locations individually with each card's Remove button, and re-add them later from the location list.
