How to use this calculator

  1. Pick the date, because daylight saving changes with the date.
  2. Enter the hour and minute in 24-hour format.
  3. Choose the zone to convert from and the zone to convert to.
  4. Read the converted time and the difference.

The formula

Convert the local time to UTC using the zone offset on that date, then add the offset of the target zone. Offsets come from the IANA time zone database in your browser, which includes daylight saving rules.

Worked example

9:30 in India on 2 November 2026 is 04:00 UTC, which is 11:00 pm on 1 November in US Eastern (UTC−5). In July, 9:00 in New York is 18:30 in India, as New York is then on daylight time (UTC−4).

Understanding your result

India has no daylight saving, so the gap with the US and Europe changes during the year. Always pick the date you are interested in.

When to use it

  • Schedule meetings across countries.
  • Check the time for a call to family abroad.
  • Plan travel or live event timings.

Assumptions and limits

Only ten popular zones are listed. Results depend on your browser's time zone data. Check important meetings with a second source.
