1 Hour Timer
One hour, counting down above. Sixty minutes, 3,600 seconds: the unit most things are billed, booked and parked in, with a tone when it reaches zero.

Nothing plays until you press start.
An hour, in numbers
An hour is 60 minutes and 3,600 seconds. Unlike most block lengths it divides cleanly, which is the whole reason the day is cut this way. Every row below adds up to exactly one hour.
| Split | Blocks |
|---|---|
| 2 x 30 minutes | Two halves |
| 3 x 20 minutes | Thirds |
| 4 x 15 minutes | Quarters |
| 6 x 10 minutes | Short rounds |
| 12 x 5 minutes | Drills and intervals |
| 2 x (25 + 5) | Two pomodoro pairs |
What people set an hour for
Parking, a billable hour, an exam paper, a slow bake, a wash cycle, a lesson, a nap you have decided is allowed to be long. It is also the honest length for anything you have told yourself will take twenty minutes.
Before you rely on the tone
An hour is long enough that a phone will have locked itself several times over. The count is taken from your device clock, so a background tab is still accurate when you look, but the sound may not play on a sleeping phone. Do not lean on it for anything where a missed alarm costs you – medication, an exam, or a cooking step that burns.
Nearby lengths
Half of this is the 30 minute timer, double is the 2 hour timer, and 45 minutes is the common working slice. To count up instead of down, use the stopwatch.
