Free online time zone converter

This time zone converter turns a time in one part of the world into the local time everywhere else. Set your source zone and time, then add as many cities as you like to see them all lined up — perfect for scheduling calls, launches and deadlines across regions.

Why time zones are tricky

  • Offsets vary — zones range from GMT-11 to GMT+14, and some are offset by 30 or 45 minutes.
  • Daylight saving — many regions shift by an hour part of the year, so the gap between two cities is not fixed.
  • Date rollover — a morning meeting for you can be late the previous night, or the next day, for a colleague.

Plan meetings with confidence

Because the converter uses your browser's built-in time zone database, daylight saving is handled automatically for the exact date you choose. It runs entirely in your browser, so it is instant, private and works offline.

Frequently Asked Questions

How do I convert time between two time zones?

Pick the source time zone, enter a date and time, then read the equivalent time in each target zone below. Add as many zones as you need to compare them side by side.

Does this handle daylight saving time (DST)?

Yes. The converter uses your browser's built-in time zone database, so daylight saving changes are applied automatically for the exact date you choose.

What does the GMT offset next to each city mean?

It shows how far that zone is ahead of or behind UTC on the selected date, for example GMT+06:00 for Dhaka. The offset can change across the year because of daylight saving.

Can I use it to plan a meeting across regions?

Yes. Set the meeting time in your own zone as the source, then add the zones of everyone attending to instantly see the local time for each person.

Why is the date sometimes different in another zone?

When zones are far apart, a time in one place can fall on the previous or next calendar day elsewhere. That is why each result shows its own weekday and date.

Is my data private?

Yes. All conversions run entirely in your browser using the Intl time zone data. Nothing is sent to a server, and the tool works offline.
