Date & TimeLOCALRuns in your browser
Timezone Converter
Convert a wall-clock time from one IANA timezone to several others, with correct DST offsets, abbreviations, and day rollover.
This tool handles input and primary processing in your browser and is designed not to send the input to QuickKit’s server.
Times by zone
UTC instant:—Unix seconds:—
| Zone | Local time | UTC offset | Abbrev. | Day |
|---|
How it works
Enter a local date and time with no offset, pick the zone it belongs to, and list the target zones (IANA names such as Asia/Tokyo). Offsets are computed from the browser's timezone database for that exact date, so daylight saving is handled automatically. Times that fall in a spring-forward gap do not exist and are flagged; times in a fall-back overlap resolve to the earlier instant. This tool does not use your location and sends nothing to a server.
