About Time Zone Converter

The Time Zone Converter takes a date and time in one city and shows the exact corresponding time in another — across 40+ major time zones from Los Angeles to Auckland. It's the easy way to schedule calls, webinars and deadlines with people around the world.

Daylight saving time is handled automatically for the specific date you pick, so a 9 AM New York meeting converts correctly whether it lands in EST or EDT. The tool also shows each zone's UTC offset and how many hours apart the two locations are.

Conversions run on your device using the browser's built-in time zone database — always up to date, nothing uploaded.

How to Use the Time Zone Converter

  1. Pick a date and time (it defaults to now).
  2. Choose the time zone the time is in, and the zone you want it converted to.
  3. Read the converted date and time — note it may fall on a different day.
