Converters & time math
Time zone converter
Translate any moment from one city to another. Pick a source and a target, set the date and time, and read off the exact converted time — daylight saving handled for you, computed right in your browser.
Questions & answers
- Does the converter account for daylight saving time?
- Yes. Each conversion resolves the real UTC instant using the source city's offset for that exact date, so spring-forward and fall-back shifts are applied automatically on both sides.
- Is my data sent anywhere?
- No. Every calculation runs locally in your browser using the built-in Intl time-zone database. Nothing is uploaded or stored on a server.
- Can I convert a future or past date?
- Yes. Set any date and time in the source city and the target time updates instantly, using the correct historical or upcoming offset for that day.
