FAQ

Does it handle daylight saving time?

Yes. Offsets are looked up for the exact date you pick, so a New York–London call is 5 hours apart most of the year but 4 hours for a few weeks in March and October/November.

What happens with a time that doesn’t exist because of DST?

When clocks spring forward (e.g. 02:30 is skipped), the converter uses the first valid time after the gap.
