How it works
Convert UTC to local time zones, or local time back to UTC.
- Keep UTC as the source or destination.
- Select a named city or IANA time zone for the local side.
- Enter the date as well as the time so seasonal rules can be applied.
Example
12:00 UTC converts to 21:00 in Asia/Seoul throughout the year because Seoul stays at UTC+09:00.
How accuracy is handled
UTC never observes daylight saving time; the selected local IANA zone may change offset by date.
Privacy: Inputs are validated and calculations use calendar-aware IANA time-zone rules.

Frequently asked questions
Is UTC affected by daylight saving time?
No. UTC does not move seasonally.
Why use a named zone instead of an offset?
Named zones preserve seasonal and historical clock rules.
