Between a break and a full hour
If 10 minutes feels trivial and 25 feels heavy, 20 is the middle. Pair it with the 5 minute timer for a 20/5 rhythm, or jump to 60 minutes when you have a longer block.

Twenty-minute countdown
Twenty minutes, loaded and waiting
The countdown starts at 20:00 on this page. It fits a short workout circuit, a talk rehearsal, or a deep-work slice that is not quite a Pomodoro. Start, pause, or add a minute without leaving the dial.
Twenty minutes is a common “serious but finite” length: long enough to enter the task, short enough that the alarm feels like a gift. Keep the laptop lid open in another room; notifications can still fire if you allowed them.
-
01
Start at 20:00
Press Start for a twenty-minute countdown. Queue another preset while it runs if you already know what comes next.
-
02
Start the countdown
Press Start or Space. Progress updates on a circular dial, and the face shows when the timer ends. Pause anytime, add +1 min, queue another timer, or go fullscreen / sleep for a distraction-free display. The tab title shows remaining time while you work elsewhere.

03
Hear the alert & keep going
When time is up, stop the alarm with one tap. Start the next queued timer, review local history, export CSV, or copy a shareable link. A refresh restores an in-progress countdown on this device.
What you get
- Presets & quick lengths Jump to common seconds, minutes, and hours, or named timers like study and classroom. The Countdown pane still offers weekdays, times of day, and a custom datetime — holiday countdowns are on the Online Countdown tool.
- Background-tab accuracy Countdown uses deadline math so it stays correct when the browser throttles hidden tabs.
- Sounds, notifications & wake lock Choose alert sounds and ring length, get a desktop notification when finished, and keep the screen awake while running.
- Fullscreen & sleep mode Go fullscreen for a large dial display, or sleep to dim the whole page so only the countdown stays visible.
- Up-next queue While a timer is running, tap presets to queue up to three countdowns and start the next when you are ready.
- Embed widget Drop a compact countdown on your site with custom colors, size, skin, and default duration.
Frequently asked questions
Setting the dial, presets, alerts, and embeds — quick answers.
Why use a 20 minute timer instead of setting 20:00 myself?
This URL is meant for search and sharing: everyone lands on the same 20:00 start. You can still edit the dial if you need 20:15.
Can I embed a 20 minute timer on a website?
Yes. The embed builder on this page copies an iframe. Set default seconds to 1200 if you want visitors to start at 20 minutes inside the widget.
Will the 20 minute timer keep the screen awake?
If you enable wake lock (sleep/wake controls on the stage), the browser can request that the display stay on while the countdown runs.
What happens at zero?
The alarm overlay appears. Stop the sound, start the next queued timer, or reset. History on this device records the completed 20-minute run.
