60 minute timer, one hour, counted for you.

A 60 minute timer, or 1 hour timer, counts down 3,600 seconds and rings at zero. The numbers show hours, minutes and seconds, starting at 1:00:00. This timer has soft cues at halfway and with one minute left, a label, rounds, full screen mode, and an optional notification. It keeps its time as a clock time, so it stays right in a background tab and after a reload.

How to use the 60 minute timer

1. Press Start or the space bar. The countdown begins at 60:00 and the line under the numbers shows the clock time it ends.
2. Pick a label under What is it for?, or type your own in Label. It shows above the countdown, in the tab title and in the alarm notification.
3. Choose Rounds if you want the 60 minutes to repeat. A single bell marks the end of each round and the next one starts at once.
4. Pick the alarm Sound and the Volume, and press Hear the sound to check it before you start.
5. Tick a soft cue if you want one: Soft chime at halfway, Soft chime when 1 minute is left or Tick the last 10 seconds.
6. Press Pause to hold the time and Resume to carry on. +1 min adds a minute. When it rings, press Stop the alarm, or Start again to run it once more.

Keeping a one hour timer alive

A long timer has more that can go wrong than a short one, so check these before you start.

• Keep the computer awake. A sleeping computer cannot ring. Plug it in, or change the sleep setting, for the hour.
• Keep the tab open. You can use other tabs or apps. The tab title shows the time left, such as 31:05 · Deep work.
• Turn on the notification. Tick Show a notification too. If you are away from the speakers, a message still waits.
• Check the sound first. Press Hear the sound. A bell you cannot hear after an hour is the worst failure.
• On a phone, keep the page on screen. Phones may pause pages that are not in view, so the alarm may wait until you come back.

If the page closes

The timer saves the clock time it should end, in this browser. Reload or reopen the page and it carries on from the right time. If the hour finished while the page was closed, it shows the time it ended. Click once on the page after a reload so the browser lets the alarm play again.

Timed papers and classes

For an exam or a class, put the timer in full screen and place it where everyone can read it. The exact time allowed comes from the paper or the organiser, not from this page, so check it and use Any other time if it is not an hour. The halfway chime plays when 30:00 is left and the one minute chime at 1:00, if you ticked them; leave them off if sound would disturb the room.

Rounds of one hour

60 minutes in other units

For a break inside the hour, the Pomodoro timer splits work and rest for you. To count up instead, use the stopwatch.

Ways to divide an hour

A whole hour is easier to use when it has parts. Four blocks of 15 minutes give 4 × 15 = 60. Two halves of 30 give 30 + 30 = 60. A block of 50 with a break of 10 gives 50 + 10 = 60. Choose Rounds if you want the same length each time; for a 50 and 10 split, run the 50 with Any other time and press Start again for the 10. The halfway chime plays when 30:00 is left, which is the point to check progress.

Common problems

• The digits look different. Past an hour the display shows h:mm:ss, so one hour is 1:00:00 and then 59:59.
• It rang and then stopped. The alarm rings for up to a minute, or three times if Keep ringing is off. Press Start again to run another hour.
