Convert a date and time between world time zones, with daylight saving handled.
Uses your browser’s time zone data — private and instant.
How do you convert a time between time zones?
Pick a date and time in one zone and the converter shows it in another, using your browser's built-in IANA time zone database so daylight saving is handled automatically for that date rather than a fixed offset. For example, 21 June 2026, 12:00 in New York is 21:30 the same day in India (IST).
Understanding your result
Because it uses live time zone rules, the result reflects daylight saving in effect on the date you choose, not a fixed offset.
Worked example
