Send it to anyone. They see the same clock, counting to the same second, with nothing to sign up for.
Frequently asked questions
How can a link work with no account?
Because the countdown is the link. The moment and the name are written into the address as ordinary parameters, and the page reads them when it opens. There is nothing on a server to look up, and nothing to expire.
Will someone in another country see the same numbers?
Yes. The link carries the instant itself, counted from a fixed point in time, not the hour showing on your clock. Each person's page then shows that instant in their own zone, and all the countdowns agree.
Does it keep running if I close the tab?
There is nothing to keep running — the clock is worked out from the moment in the link each time the page opens. Close it, open it a week later, and it is still counting correctly.
Why did the seconds jump when I came back to the tab?
Browsers slow down tabs that are not on screen, so the ticking pauses. The page reads the real time again as soon as you return, which is why the figures catch up in one step rather than drifting.
Can I count down to something in the past?
Yes. Pick a date that has been and it counts upward instead, saying how long ago the moment was. It is the same arithmetic read the other way.
Counting to one moment
Pick the moment, give it a name, and copy the link. Anyone who opens it sees the same clock, counting to the same second, wherever they are.
- A launch, a deadline, a flight, an exam — anything with one agreed moment works.
- Give it a name before you send it. A clock with no label is a clock nobody acts on.
- The address is the whole countdown, so a bookmark is as good as an account.
- Past dates count upward, which is a fair way to read how long something has been running.
Full specification
| What you set | A date, a time to the minute, and a name to put above the clock. |
|---|---|
| The shared link | The moment and the name are carried in the address as plain parameters. Nothing is stored, so there is nothing to expire. |
| Time zones | The link carries the instant, not the wall clock, so everyone counts to the same second wherever they are. |
| After it passes | It keeps counting, upward, and says how long ago the moment was. |
| Background tabs | A hidden tab is slowed by the browser, so the clock is set right again the moment you come back. |
| Where it runs | In your browser tab. No countdown is sent anywhere or kept. |
| Price | Free |
| Account required | No |
