How to use this calculator

Choose two city-labeled IANA time zones to see their current clocks and UTC offsets. Turn on the meeting window to convert a source time and compare it with destination availability.

What this means

The time difference is based on the selected zones' rules at the relevant moment, so daylight saving changes are handled automatically. Unusual offsets such as India's half hour and Nepal's quarter hour are preserved.
