The short answer
A 1 hour timer counts down 60 minutes and rings at zero. Press Start above; it shows the time left in your browser tab, keeps going in the background and survives a reload. One hour is a good length for a deep-work block, a long workout, cooking a proper meal or a screen-free evening.
What fits in 1 hour?
An hour is enough for one important thing. Decide what it is before you press Start.
- A deep-work block. One project, phone in another room. Put it on your calendar like a meeting; see time blocking.
- A screen-free hour. Phone in a drawer, timer on the laptop or kitchen tablet. Ideas in how to reduce screen time.
- Two Pomodoros. 25 minutes of focus, 5 of break, twice. An hour of steady work that does not wear you out.
- A long walk or run. One hour is 60 of the 150 weekly minutes of moderate activity the CDC suggests for adults.
- Plan your week. Look at the calendar, choose three priorities and block time for each with the daily routine planner.
How to use the 1 hour timer
- Press Start. The timer is already set to 1 hour. The space bar starts and pauses it too.
- Need a different time? Type it in the box, such as 7, 7m 30s or 7:30, and press Set. Or tap another preset.
- Make it big. Full screen (or F) shows only the countdown. Kids view shows a big colored disk that shrinks as time runs out.
- When it rings, press Stop alarm or the space bar. Restart runs the same 1 hour again; +1 min snoozes for a minute.
The timer saves the moment it will end on your device, so it stays accurate in a background tab and after a reload, and the time left shows in the tab title. The page has to stay open for the alarm to play.
Frequently asked questions
Is a 1 hour timer the same as a 60 minute timer?
Yes. It counts down 60 minutes, shown as 1:00:00, then 59:59 and so on. To set 60 minutes from the box, type 60, 1h or 1:00:00.
How do I set 1 hour 30 minutes?
Type 1:30:00, 1h 30m or 90 in the box and press Set. A plain number is read as minutes, and two colons mean hours, minutes and seconds.
Will the timer still be right after an hour in a background tab?
Yes. It works from the time the hour ends, not by counting ticks, so a slowed-down background tab cannot make it drift. The alarm is queued on the audio clock, which keeps running while the page is open.
