How to use it
Choose the type
“To a date and time” for an event, or “Timer for a duration” for minutes.
Set the time
Pick the date (Gregorian or Hijri) and time, an upcoming occasion, or a ready duration.
Share or wait
Copy the link to share it; the alarm sounds at the end even when the tab is in the background.
So you don’t miss it
Turn the sound on: browsers block sound until you tap the page once; tap “Test sound” to check.
A sleeping device stays silent: if the phone screen goes off or the computer sleeps, the browser pauses; the countdown is right again when you come back. For important alarms, use your phone’s alarm.
Links work anywhere: the link carries the moment in UTC, so a friend in another country sees the same time left in their own time zone.
FAQ
How do I make a countdown to a date?
Choose “To a date and time”, pick the date and time or an upcoming occasion, add a title, then copy the link to share it.
Does the timer keep running in another tab?
Yes. Time is read from your device clock, not counted, and the alarm is scheduled ahead, so it stays accurate in the background.
Is my countdown saved?
Yes, it stays in your browser and continues when you come back; you can also bookmark the link.
