About the Time Zone Converter
Convert a date and time between any two time zones instantly — EST to PST, UTC to IST, London to Tokyo, or any of 400+ IANA zones. Daylight saving time is handled automatically for the exact date you pick, and the tool shows how many hours ahead or behind the target zone is. Perfect for scheduling meetings, calls, and launches across countries.

- 01Pick the “from” and “to” time zones (your local zone is preselected).
- 02Choose the date and time in the “from” zone.
- 03Read the converted time and the hour difference — DST is applied automatically.
Frequently asked questions
Does it handle daylight saving time?
Yes — conversions use the real time zone rules for the exact date you choose, so DST transitions are always correct.
Why does the hour difference change with the date?
Zones enter and leave daylight saving on different dates, so the gap between two zones can shift by an hour depending on the time of year.
