How it works

Three free tools, no sign-up. Pick one below to see how it works.

1. Browse a category

Birthdays, holidays, sporting events and more, all under All Countdown Events. Each one links to a curated page for that specific occasion.

2. Open the page

Every countdown page shows a live clock (days, hours, minutes and seconds) counting down to that exact moment, calculated correctly in your local time zone.

3. Share the link

Send the page link by WhatsApp, text, email or anywhere else. Everyone who opens it sees the same live countdown. They can add the moment to their calendar with one tap.

4. Celebrate at zero

When the clock hits zero, the page erupts: confetti, fireworks, or another celebration effect matched to the occasion. Anyone visiting after the moment sees the celebration right away.

1. Set a time

Type hours, minutes and seconds, or tap a preset. You can also jump straight to a ready-made timer — a 5-minute, 10-minute or egg timer — with the time already set.

2. Press start

The timer counts down. It keeps running if you switch tabs or lock the screen, and the tab title shows the time remaining so you can glance back anytime. Pause and resume whenever you like.

3. It rings at zero

When the timer reaches zero it sounds an alarm and flashes Time's up. Press Space to start or pause, hit Full screen for a big across-the-room display, or Reset to run it again.

1. Press start

Hit Start (or Space) and the stopwatch counts up from zero in minutes, seconds and hundredths.

2. Take laps

Tap Lap to record a split without stopping the clock. Each lap is timed from the previous one and added to a list, so you can compare them afterwards.

3. Stop & reset

Pause and resume as often as you need. Reset clears the clock and the laps back to zero, and Full screen gives you a big, easy-to-read display.
