How to set a 5 hour timer

This 5 hour timer counts down from 5:00:00 (300 minutes) and plays an alarm when time runs out. It shows the time it will end, so a glance tells you if you're on track.

Setting it up

  1. Press Start.
  2. Read the end time on screen and keep it in mind for planning.
  3. Leave the page open in a tab. You can work in other tabs and still see the time left in the tab title.

When people need five hours

A long study or work block. Five rounds of the 50/10 timer fill exactly five hours, giving you a short break every hour.

A volunteer or event shift. Know when your shift ends without checking your phone constantly.

Screen-time or charging limits, rest periods, and reminders to check on something later in the day.

Need 1.5 or 2.5 hours instead?

Many people searching for long timers actually want a different length. Use the 1 hour 30 minute timer for 1.5 hours, or press Set Time and enter 2 hours 30 minutes for a 2.5 hour timer.

Honest limits

The alarm only plays while the page is open. On a phone, the screen-awake feature depends on your browser, so keep the phone plugged in and check that it won't lock and close the tab over five hours.
