Countdown Generator
A live countdown to any moment, shareable as a link.

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 to use it
Set a date, time, and time zone to start a live countdown, then share the link. Everyone sees the same countdown. No account needed, and it never expires.
Counting down to a holiday, a launch, a wedding, or a birthday? Pick the date, time, and time zone, give it a name, and the countdown starts straight away.
Copy the link to share it. Everyone sees the same countdown, ending at the same moment — even in different countries (8 pm in London is 5 am in Tokyo, and the page shows that).
The link never expires, because the whole countdown is stored inside the link itself. Nothing is saved on our end, so there’s nothing that can be deleted or switched off.

FAQ
How do I make a shareable countdown?
Set the date, time, and time zone, then copy the link. Anyone who opens it sees the same countdown.
Does the link expire?
Never. The countdown is stored in the link itself, not on a server.
Do people in other time zones see the same countdown?
Yes. It ends at the same moment everywhere, and the page shows what time that is locally.
Can I put it on my own website?
Not as a widget — it’s a page to share.
What happens when it reaches zero?
It keeps going and counts up, showing how long ago it was.
Is anything about my countdown saved?
No. It only exists in the link and your open tab.
How it worksFor the curious
The target date, time, zone, and title are encoded as URL parameters, and the opening browser recalculates the countdown from them. No record exists anywhere, so the link cannot expire or be deleted and does not depend on a database. The trade-off is a long URL; a shortened one would mean storing the countdown on someone’s server.
The target is a single fixed instant, so it reaches zero simultaneously everywhere. For a moment that arrives at the same local clock time in each place, use an all-day calendar entry instead. To plan a call, check the time on everyone’s clock.
The .ics file is the same one the .ics event generator writes, storing the time as an exact UTC instant. After zero, the countdown keeps running and counts up.
