About

This site converts time between cities and time zones and helps plan meetings across them. It is fast, free and works without an account.

Up to 10 places can be compared at once. Every page, from a city's current time to a conversion between two time zones, is calculated live for the date you pick.

Where the data comes from

Time zone rules come from the IANA time zone database (tzdata) built into your browser and our servers, so daylight saving changes are applied exactly.

Place names, coordinates and populations come from GeoNames (CC BY 4.0). Sunrise and sunset are calculated from coordinates and can differ by a minute or two from local almanacs.
