How it works
Enter a date and time, pick the time zone that time is in, and pick the zone you want it converted to. The tool interprets your entry as a wall-clock time in the source zone, works out the exact moment that represents, and shows the matching local time in the target zone — with daylight saving applied automatically for that specific date using your browser's built-in time zone data. The world clock below shows the current time in major cities, updating every second. Everything runs locally in your browser.

FAQ
How do I convert a time between two time zones?
Enter the date and time, choose the zone it's in, and choose the zone you want it converted to. The result shows the matching local time in the target zone, along with the difference in hours.
Does it handle daylight saving time?
Yes. The conversion uses your browser's built-in time zone database, so daylight saving shifts are applied automatically for the specific date you enter.
What is the world clock?
It shows the current local time in a set of major cities, updating every second, so you can see at a glance what time it is around the world.
Is anything uploaded?
No. All time calculations run in your browser using its built-in internationalization data. Nothing is sent to a server.
