About MinuteTimer
Simple online timers that are ready when you are.
MinuteTimer is a set of free online timers. Open a page, check the time and press Start. There is nothing to install and no account to create.
What you can use
- The online timer for any duration from 1 second to 24 hours.
- Ready-to-start minute, second and hour timers, such as the 5 minute timer and the 40 minute timer.
- A classroom timer with big numbers, an activity label and sound off by default.
- An online stopwatch with lap times.
How the timers are built
Every countdown uses the same engine. It stores the finish time instead of counting ticks, so the display stays correct after a tab has been in the background. Pause, resume and reset behave the same on every page, and no preset starts until you press Start.
The alarm sounds are generated in your browser with the Web Audio API. No audio files, fonts or scripts are loaded from other websites.
What we do not promise
A web page is not an alarm clock. Browsers may pause pages on locked or sleeping devices, and closing the tab stops the timer. The help page explains these limits in detail.
Editorial standards
- Pages describe what the tools really do. Where a timer page mentions a common use, such as handwashing or brushing teeth, it links to the organization or study the advice comes from.
- We do not publish invented reviews, statistics or promises such as “guaranteed alarm”.
- Every page shows when it was last reviewed. Corrections sent through the contact form are checked and fixed.
- Technical claims about browsers are based on the sources listed on the help page.
Privacy and contact
The timers work without cookies, analytics or ads. Read the privacy policy and cookie policy for details, and use the contact form for questions, problems or ideas. Want to contribute a guide? See write for us.
