Time zones calculator

How it works

Pick a time and two cities to see the matching local time.

The formula

Target time = source time − source UTC offset + target UTC offset, with daylight-saving time applied where it is in force.

Worked example

9:00 in Kuwait (UTC+3) is 10:00 in Dubai (UTC+4) and, in November, 1:00 the same day in New York (UTC−5).

Good to know

• Daylight-saving dates differ between countries, so the gap can change during the year.
