1 Hour Timer
Free shareable timer - copy the link and anyone can start counting down instantly.
Why a 1 hour timer?
An hour is the unit everything else is measured against. It is the standard exam length, the default long meeting, the block most people set aside for anything described as "proper" work - and the span over which attention most reliably drifts without a visible clock.
That drift is the argument for timing it. An hour spent with the countdown in view behaves very differently from an hour spent checking the corner of a screen, because glancing at the clock is itself one of the interruptions that fragments the hour.
What people use a 1 hour timer for
- Exams and timed papers. The standard paper length, and the one worth rehearsing under real conditions.
- Deep work blocks. A full hour on a single problem, with the timer removing the need to check progress.
- Meetings and workshops. The default long slot - a shared countdown keeps the agenda honest.
- Slow cooking and baking. Roasts, breads and braises that need one hour before the next step.
- Screen-time and practice limits. An hour of practice, gaming or reading with a clear, agreed end point.

Frequently Asked Questions
Can I leave this timer running in a background tab?
Yes. The countdown is based on elapsed clock time rather than a tick counter, so it stays accurate when the tab is in the background. Some browsers throttle background audio, so keep the tab visible if you are relying on the alert.
How do I use an hour timer for exam practice?
Run it once, without pausing, from the moment you open the paper. The value is in rehearsing the pacing - knowing what twenty minutes remaining feels like - which only works if the clock runs the way it will on the day.
Can I share this link with my class?
Yes - just copy the link from the box above and paste it into your LMS, email, or messaging app. When students open it they get a 1h timer that's ready to start with one tap. No account or download needed.
Does the timer save my progress?
The timer runs entirely in your browser - progress is not saved between page loads. If you refresh or close the tab the timer resets to 1h. For a timer that auto-starts when someone opens the link, add ?autostart=1 to the URL or use the shareable timer generator.
Can I add a label to my timer?
Absolutely. Add a ?label= parameter to the URL - for example https://stopwatch.now/timer-link/1h?label=Math+Quiz. The label appears above the countdown. You can also use the timer link generator to build a labelled timer link without editing URLs by hand.
Can I make the timer auto-start when someone opens the link?
Yes. Add ?autostart=1 to the URL. For example: https://stopwatch.now/timer-link/1h?autostart=1. The timer will begin counting down the moment the page loads - no click required.
