5 hour timer
A free 5 hour timer preset to 5:00:00. Press Space to start, and the remaining time stays in the tab title while you do other things. A phone timer disappears behind the lock screen; this one stays in view. Also searched as 5 hr timer, five hour timer, 300 minute timer.
Things that take about five hours
| Task | Time | What to watch |
|---|---|---|
| Pulled pork, slow cooker on High | 5 to 6 h | Shreds easily; internal temperature well past 195°F |

| Pizza dough, slow rise in a cool room | 4 to 6 h | Doubled and airy; see the bread proofing timer |
| Road-trip leg | 5 h | Plan a stop at 2:30; set a second alarm if you drive on |
| Half-day work block | 5 h | Five 50/10 cycles fit exactly |

Five 50/10 cycles
Five hours divides neatly into five rounds of fifty minutes of work and ten minutes of rest. Use this page as the hard stop and the 50 minute timer with Repeat for the rounds. If you prefer shorter sprints, the Pomodoro timer fits ten sessions into the same window.
Medication intervals
Some medicines are taken every four to six hours. A five-hour countdown is a reasonable reminder for the middle of that range, but the label or your clinician decides the interval. This page is a timer, not medical advice.
Keep the device awake
Five hours will outlast any default screen-sleep setting. Keep the tab open, disable display sleep, and tick Notify on a desktop browser. The end time is saved, so a reload resumes the countdown, but a sleeping device cannot sound the alarm. For a fixed end time of day, the alarm clock page shows how to compute the countdown. Shorter or longer: 4 hour timer, 6 hour timer.
Frequently asked questions
Can I set a 5 hour timer and still use my phone?
Yes, as long as the browser tab stays open and the screen stays awake. Once the phone locks, the alarm is usually muted.
How do I take breaks during a 5 hour work block?
Keep this page for the overall limit and run a 50 minute timer with Repeat in another tab. Take ten minutes at each alarm.
Is this page a medication reminder?
It can remind you, but it is not medical advice. Follow the label or your prescriber's instructions for dosing intervals.
