The world's time, beautifully simple
World clock, timezone & currency converter, sun & moon, holidays, and date calculators — all in one fast, installable app that works without internet.
Everything you need
Time, made simple — for the whole world
World on Time is a fast, clean alternative to the cluttered time-and-date tools you grew up with. World clock, time zone converter, calendar, sun and moon times, weather, and public holidays — all in one place, all mobile-first, and most of it works offline.
Who it’s for
We built this for the people whose day crosses borders: remote teams, frequent travelers, developers wrangling time zones in code, and anyone with family or colleagues in another part of the world.
How the data works
Time and time zone calculations come from the official IANA time zone database — the same source your operating system uses — so daylight saving and historical offsets are handled correctly. Weather comes from Open-Meteo, and public holidays from an openly licensed dataset. Want to go deeper on how any of it works? Read our guides.
