1 Hour Countdown Timer
A full hour on screen, which is the unit most people actually mean when they say they need more time.
How to Use the 1 hour Countdown Timer
Open the timer
This page is already set to 1:00:00. Press the start button and the countdown begins, with no setup and no signup.
Press F for fullscreen
The digits scale to fill the whole screen, so the remaining time stays readable from the back of a room, a classroom or a gym.
Keep the block visible
Use the subtitle to say what the 1 hour timer is for. A countdown with a name on it is much easier to come back to.
The bell ends it
An audible alert rings when the 1:00:00 countdown reaches zero, so you never have to watch the screen to know it is over.
Why Use This 1 hour Timer
The full hour
Preloaded with sixty minutes and counting down in hours, minutes and seconds so there is never any doubt about the time left.
Built for the big screen
Fullscreen mode fills a projector, a smartboard or a TV, which is what an hour long session usually needs.
An alert that ends the session
The bell and the end state close the hour cleanly, so you are not tempted to stretch it.
Same timer for everybody
Share the link and the other person gets the identical hour countdown, including the theme.
Where This Timer Helps
An hour is the unit people reach for when they want to know how much is left in a session: an exam, a meeting, a class, a podcast, a long drive, a workout. It is long enough to lose track and short enough to plan.
This one hour countdown makes that visible. The digits fill the display, the alert fires when the hour is up, and you can share the exact timer with anybody who needs to follow the same clock.
Tips for making the most of it
- Use the subtitle to state what the hour is for, for example exam or final rehearsal.
- Split the hour mentally in two halves and give each one a checkpoint to review progress.
- If you need to restart, the reset button returns to exactly one hour.
1 Hour Countdown Timer: Frequently Asked Questions
How do I set a 60 minute timer?

Can I use an hour timer for an exam?
Yes, project it on the smartboard so students can see the remaining time at a glance, and keep the alert on for the end of the exam.
Does the countdown stay accurate if the tab is in the background?
