What does the Time Zone Converter do?

Choose a date and time and the time zone it is in, then add the zones you want to compare. The converter uses your browser’s built-in IANA time zone database, which includes the daylight saving rules for each region — so a call at 12:00 in Karachi is shown as 08:00 in London in July (BST) but 07:00 in January (GMT).

It also warns if you pick a local time that does not exist because clocks spring forward.

How to use the Time Zone Converter

  1. Choose the date and time.
  2. Choose its time zone.
  3. Add the time zones you want to compare.
  4. Copy the table to share meeting times.
