Synced to the second · No ads
Know the real time, anywhere on Earth.
Compare time across as many places as you like — synced to a network time source, accurate to the second, and always daylight-saving correct. We even tell you how far your own device clock has drifted.
Comparison board

Why Real World Clock
A world clock that respects your time.
Sync engine
Accurate to the second.
We sync to a network time source and tick on a precise loop — then show you exactly how far your own device clock has drifted. No more guessing whether the time is right.
Time zones
Always DST-correct.
Offsets and daylight-saving transitions come straight from the IANA time-zone database in your browser, so a city is never an hour off after a clock change.
Planner
Find a meeting time fast.
Drag one timeline and watch every city move together. Working hours light up green where everyone overlaps — no mental math, no spreadsheet.
Calibration
Add places your way.
Auto-detect your location, search any city or time zone on Earth, or paste exact coordinates. Whatever's fastest for you.
Sharing
Share without an account.
Your board lives in the URL. Copy the link and the exact set of places and settings travels with it. Nothing to sign up for.
By design
No ads. No clutter.
One clean surface that loads instantly. No pop-ups, no consent walls, no wall of unrelated information burying the time you came for.
