Custom countdown timer
Enter an event name, a date and a time. The countdown shows the days, hours, minutes and seconds left in real time, then counts the time elapsed once the moment has passed. The page link stores your settings, so you can copy it and share the exact same countdown with friends or coworkers.

How the countdown works
The timer compares your target moment, in your device's time zone, with the current time and refreshes several times per second. Nothing is installed and nothing is sent anywhere.
\[ \text{time left} = \text{target moment} - \text{current moment} \]
The result is split into days, hours, minutes and seconds: 1 day = 24 hours and 1 hour = 60 minutes. When the moment arrives, confetti appears and the tool starts counting the time elapsed.
Share a countdown with a link
Every setting is written into the page address as a parameter. Copy the address to bring back or share exactly the same countdown.
| Parameter | Meaning | Example |
|---|---|---|
| d | date | d=2027-07-04 |
| h | time | h=09:00 |
| t | title | t=Concert |
The time is read in the time zone of whoever opens the link. For a live event watched from several countries, use the time zone converter.
