Time Zone Converter
Convert a date and time between any time zones, with daylight saving handled automatically.

- Choose the time zone it's in (IST by default).
- Add the time zones you want to compare.
- Read the converted times side by side.
IST and the world
India Standard Time (IST) is UTC+5:30 all year; India doesn’t use daylight saving. Many other countries do, which is why the gap between India and the US or Europe changes twice a year. For example, New York is 9 hours 30 minutes behind IST in the northern summer and 10 hours 30 minutes behind in winter. This converter uses your browser’s built-in time zone database, so these changes are applied automatically for any date you pick.
Common conversions
- IST to EST/EDT (New York): subtract 10:30 (winter) or 9:30 (summer).
- IST to PST/PDT (California): subtract 13:30 or 12:30.
- IST to GMT/BST (London): subtract 5:30 or 4:30.
- IST to GST (Dubai): subtract 1:30.
- IST to SGT (Singapore): add 2:30.
Rather than doing mental maths, pick the date and time and read the result.
Scheduling across time zones
- Share meeting times with the time zone written, for example “7:30 pm IST / 10:00 am EDT”.
- Check the date, not just the time: late evening in India can already be the next morning in Australia.
- Around daylight saving change dates (March–April and October–November), double-check recurring meetings.
Many zones at once
Add several zones to see them together, useful for global teams, client calls, webinars and calling family abroad. Remove any you don’t need.
