Four hours on the clock, with a loud alarm when it's up.

04:00:00

Tip: click anywhere on the page at least once so the alarm sound can play when time is up.

What is a 4 hour timer good for?

Four hours is a half work-shift, a slow-cooker's favorite setting, and a common ceiling for deep study or writing sessions. This preset counts the whole thing down so you don't have to watch the clock.

Frequently Asked Questions

Does the timer keep running if my laptop sleeps?

No — a full system sleep pauses everything. Adjust your power settings so the display can dim without the whole device sleeping.

Can I get a sound partway through, not just at the end?

Not on this preset — it alerts once at zero. For interval alerts, pair it with our stopwatch or set several shorter timers back to back.
