90 minute timer

An hour and a half, nothing to set

This 90 minute timer shows 1:30:00, an hour and a half. Click "Start" or press the space bar: the alarm goes off after 90 minutes, and the remaining time stays visible in the tab title throughout.

What can you do in 90 minutes?

• A football match. Two halves of 45 minutes make 90 minutes of play, not counting stoppage time or the break. For a Sunday league game, pause the timer at half-time and resume it at the restart.
• A long nap. A sleep cycle is often put at around 90 minutes, though it varies a lot from person to person and night to night. Some people time a nap to this length hoping to wake at the end of a cycle. There is no guarantee.
• A long study block. Ninety minutes with a 5 to 10-minute break in the middle: "Pause" halfway, "Resume" when you are back.
• A film. Plenty of feature films, especially animated ones, run for about an hour and a half. The timer can signal bedtime.
• A mock exam. For a 90-minute paper, sit a past paper in real time without looking at the clock.

Tips

The "Common durations" buttons stop at 60 minutes, so bookmark this page: it always opens at 1:30:00. Over such a long stretch, stop your computer from going to sleep, and on a phone keep the screen on, especially for a nap.

Frequently asked questions

How do I set 1 hour 45 or 2 hours?

Type 1 in "Hours" and 45 in "Minutes", or 2 in "Hours" and 0 in "Minutes", then click "Start".

Can the countdown drift over an hour and a half?

No. The remaining time is worked out from the finish time, so it stays exact even when the tab is in the background. Just do not close it.
