Countdown timer

Set a target date and time to count down live, and share it with a link.

How Countdown timer works

Countdown timer counts down live to a specific date and time, a launch, a birthday, a deadline, with seconds ticking in real time and a link you can share so others see the same countdown. It is the tool for an exact moment, down to the second.

If you instead want a plain number of days until a date (no live ticking), the Days until a date tool is more direct; to measure time elapsed since a past date, use Time since a date. The target you set is encoded directly into the shareable link, so whoever opens it recomputes the same countdown from the URL.

Frequently asked questions

How is this different from "Days until a date"?

Countdown timer ticks live down to the second toward a date and time and is meant to be shared or displayed. Days until a date just gives a static day count, better when you only need the number, not a live clock.

How does the shareable link work without a server?

The target date is encoded into the URL itself. Whoever opens the link recomputes the countdown locally in their own browser, no event data is stored on any server.

Is the date I enter sent anywhere?

No. Every value is computed in your browser, on your device. The date you enter never leaves your machine and nothing is stored between visits.

Does it work offline?

Yes, once the page has loaded. Because the processing happens on your device, you can disconnect from the network and the tool keeps working. This is the clearest proof that your data never leaves your machine.

Is it free? Do I need an account?

It is completely free and requires no sign-up. There are no watermarks, no daily limits and no tracking cookies needed to use the tool.
