Pick a datetime, select source and target zones, and see formatted local times with UTC offsets and hour difference. Essential for remote meetings, flight planning, cricket/live event scheduling, and international calls. 100% client-side using your browser's Intl API.

Tips & common mistakes

  • Search timezones by city or region name in the filter box.
  • IST (Asia/Kolkata) is UTC+5:30 year-round — no daylight saving.
  • US zones observe DST — offsets change seasonally; the tool uses current rules.
  • Pair with Unix Timestamp Converter for epoch ↔ datetime workflows.

Frequently asked questions

How do I convert IST to EST?
Set source zone to Asia/Kolkata (IST), target to America/New_York (EST/EDT), enter your datetime, and read the converted result.
Does this handle daylight saving time?
Yes. The browser Intl API applies current DST rules for each timezone based on the date you enter.
How many time zones are supported?
All IANA time zones supported by your browser — typically 400+. Common zones are listed first; search to find others.
What is the difference from Unix Timestamp Converter?
Unix Timestamp Converter converts epoch numbers to dates. Time Zone Converter converts a wall-clock time from one zone to another.
Is my data uploaded?
No. Conversion uses local browser APIs only.
