World Clock

Live current time in multiple zones at once — saved between visits.

About the World Clock

Add as many IANA time zones as you like — each cell shows the live local time, date and short zone abbreviation, updated every second. Your selected zones are saved in your browser so they persist across visits.

Useful for distributed teams, travelers, or anyone who needs a quick at-a-glance view of "what time is it everywhere."

How it works

For each zone you add, the World Clock formats the current moment in that zone's wall-clock time using Intl.DateTimeFormat. The display refreshes every second. Your zone selections are saved to localStorage so they persist between visits.

Examples

Frequently asked questions

How many zones can I add?
Up to 12 at once. Reset returns to the default 6.
Are my zones saved between visits?
Yes — your selections are stored in your browser's localStorage.
Does the clock keep running if I close the tab?
No — it updates only while the page is open. The next time you load it, the times reflect the moment of load.
