Time Zone Converter
Converts a specific moment from one time zone to as many others as you like, with UTC offsets and day-change markers. Uses the full IANA time zone database built into your browser, including all daylight saving rules, past and future.

Notes
- Daylight saving time is applied automatically for the exact date you pick: the same two cities can be 5, 6 or 4 hours apart depending on the week of the year.
- During a spring-forward gap (e.g. 02:30 on the night clocks jump) the entered wall time does not exist; the converter resolves it to the moment after the jump.
- Everything runs locally in your browser; nothing you enter is sent to any server.
