# Time Zone Converter

> Convert a time between any two time zones, with daylight saving handled correctly.

To convert a time between zones, enter the date and time and choose the source and target zones. Offsets are calculated for that specific date using the browser's IANA timezone database, so daylight saving is applied correctly rather than assuming a fixed gap.

## FAQ

Countries start and end daylight saving on different dates, and some do not observe it at all. London and New York are five hours apart for most of the year but four hours apart for two short windows in spring and autumn.
