World clock FAQ
How accurate is this world clock?
It reads the clock from your device and applies each zone's current UTC offset from the IANA time zone database, so it is as accurate as your device's clock — usually within a second of real time.
Can I save my own list of cities?
Yes. Add or remove cities and the list is stored in your browser's local storage, so it is there next time you open the page. Nothing is sent to a server and no account is needed.
Why does one city show a different date?
Time zones span more than 24 hours end to end, so when it is late evening in Los Angeles it is already the next day in Tokyo. Each row shows its own weekday and date for exactly that reason.
