45 Minute Timer with Alarm

A free 45 minute timer, ready when you are. It starts at 45:00 and counts down while you get on with things, then a chime plays when time is up.

Need to set a timer for 45 minutes? This one is ready to go. It's already set to 45:00, so all you have to do is press Start. You don't need to type anything in, install an app or create an account.

As it counts down, the ring around the clock gets shorter so you can see the time left without reading the numbers. The countdown also shows in your browser tab, so you can work in another tab and still see it. When it reaches zero, a chime plays. Check that your sound is on.

People use a 45 minute timer for things like a study block, a gym class, a meeting, roasting vegetables, or one section of an exam.

Frequently Asked Questions

How many seconds are in 45 minutes?

45 minutes is 2,700 seconds. The timer shows it as 45:00 when it starts.

Will the alarm still go off if I switch tabs?

Yes. The timer goes by your device's clock, so it doesn't slow down when the browser puts the tab in the background. Keep the tab open and your volume up. On some phones the browser can't play sound while the screen is locked, so it's safer to keep the screen on.

Can I change the time or make it fullscreen?

Yes. Tap Edit to set any hours, minutes and seconds you like, or tap Fullscreen to show a big countdown on a classroom board, TV or kitchen tablet.

What is a 45 minute timer good for?

45 minutes works well for a study block, a gym class, a meeting, roasting vegetables, or one section of an exam. For longer sessions, go fullscreen on a spare screen or tablet so everyone in the room can see how much time is left.

Can I share this timer or put it on my website?

Yes. Tap Share to copy a link (it includes any custom time you set), or copy a short code that embeds the timer on your own website or classroom page.
