World Time Zone Converter

Enter a date and time for a reference city, and see the local time in major cities around the world at a glance.

How to use

Choose a reference city, enter a date and time in that city's local time, then click "Convert" to see the same moment expressed in the local time of other major cities. Daylight saving time is applied automatically for cities that observe it, based on the date you enter.

Frequently Asked Questions

Does this account for daylight saving time (DST)?

Yes. This tool uses your browser's built-in time zone database, so it automatically calculates whether a given city is observing daylight saving time on the date you entered.

What happens if I don't enter a reference time?

If you leave it blank, the conversion uses the current time at the moment you click Convert.
