L'heure exacte maintenant.

Exact Time Now is a live world clock and time-zone reference for anyone who needs to know what time it is, anywhere on Earth, to the second. Pick a city below to see its current local time alongside sunrise, weather, public holidays and the difference from your own time zone. Or use the meeting planner and side-by-side compare tool to coordinate work across continents without the usual mental arithmetic.

How we keep time accurate

Every clock on this site is rendered from the official IANA Time Zone Database — the same dataset used by every major operating system. We refresh it whenever IANA publishes new daylight-saving rules so the times you see reflect the latest government changes, not last year’s. Page renders are synchronised against an NTP-aligned server clock, so the second-hand on screen is accurate to within a few hundred milliseconds of UTC. Weather, public holidays and sunrise data come from Open-Meteo, Nager.Date and sunrisesunset.io respectively, and are cached briefly so the page stays fast.

Who it’s for

Remote teams scheduling cross-time-zone meetings, traders watching market opens in another hemisphere, travellers checking what time to call home, and developers who just need a reliable second-hand on the web. No accounts, no installs — just open the page and the clock starts ticking.
