Countdown Generator
A live countdown to any moment, shareable as a link.
By opening this website or using its tools, you agree to our Terms and Privacy Policy.
The target is fixed to this zone, so everyone you share the link with counts down to the same moment — not to that clock time where they are.
Pick a target date to start the countdown.

How it works
To create a shareable countdown, set a target date, time, and time zone above — the countdown starts immediately and the link below reproduces exactly the same countdown for anyone you send it to, with no account and no expiry.
The countdown is described entirely by its own link. The target date, the time, the zone, and the title all travel as parameters in the URL, so when someone opens it their browser recalculates the same countdown from the same values. There is no record of it anywhere — nothing was saved when you made it, and nothing is looked up when it is opened. The practical consequence is that the link cannot expire, cannot be deleted by someone else, and does not depend on this site keeping a database of countdowns alive.
The trade-off is a long URL. A shortened link would be tidier but would mean storing your countdown on someone’s server and depending on that service continuing to exist — which is why link shorteners are the most common reason old shared countdowns are dead.
Choosing a time zone is what makes the countdown mean the same thing for everybody. The target is fixed to a single instant, so a countdown set for 20:00 in London finishes simultaneously for a viewer in Tokyo — at 05:00 their time, not at 20:00 theirs. If you want the opposite, a moment that arrives at the same clock reading in each place, a countdown is the wrong shape for it: use an all-day calendar entry instead. If the moment is a call between several places, check the time on everyone’s clock before fixing the target.
The .ics download puts the same moment in your own calendar so you get a reminder rather than having to remember to open the countdown — the same file the standalone .ics event generator writes, with the time stored as an exact instant. For a fixed count of days until a date rather than a live clock, the date difference calculator is enough.
FAQ
How do I make a shareable countdown?
Set the target date, time, and zone above, then copy the link. Anyone who opens it sees the same countdown running to the same moment.
Does the link expire?
No. The countdown is encoded in the link itself rather than stored anywhere, so there is nothing that can be deleted or time out. The link works as long as this page exists.
Do people in other time zones see the same countdown?
Yes. The target is a single fixed instant, so the countdown reaches zero at the same moment everywhere — it just corresponds to a different local clock time in each place, which the page shows.
Can I embed the countdown on my own site?
Not as a widget. The link is a page you share rather than something designed to be framed. For a site of your own, a countdown is a few lines of JavaScript against a fixed target timestamp.
What happens when the countdown reaches zero?
It keeps running and counts up instead, showing how long ago the target passed. Nothing disappears.
Is anything about my countdown stored?
No. It exists only in the link and in the tab you have open. The network monitor on this page confirms nothing is transmitted while you build it.
