About TimeIs.today
Accurate, ad-light time information for every city in the world.
What we do
TimeIs.today answers one question reliably: what time is it in X? Every page shows the current local time for a city, country or time zone, together with its UTC offset, daylight saving status, sunrise and sunset times, moon phase and practical time differences. All 170,000+ city pages are server-rendered, so the answer is readable even without JavaScript.
Where our data comes from
We do not guess time zones. City locations and populations come from GeoNames (CC BY 4.0), and all time zone rules — offsets, abbreviations, historical changes and daylight saving transitions — come from the IANA time zone database, the same source used by operating systems worldwide. Sunrise, sunset and prayer times are calculated from standard astronomical algorithms, so they work for every location on Earth.
Free tools, free API
Beyond city pages, the site offers a full toolbox: an online clock, countdown timer, stopwatch, alarm clock, time zone converter, meeting planner, world clock, age calculator, Unix timestamp converter and embeddable clock widgets. Developers can use our free JSON time API for free, no key required.
Independence
TimeIs.today is an independent project. We are not affiliated with any other time website. If you spot an error in a city's time or data, tell us — corrections ship quickly.
