20 Minute Timer — Free Online Countdown

Need a 20 minute timer? Press start above — it's free, runs in your browser, keeps counting in the background and chimes when time's up. Adjust with −1/+1 or show it full screen.

What to Do With Twenty Minutes

• A power nap — naps of around 10 to 20 minutes are widely recommended because they're short enough to avoid waking up groggy from deep sleep. Set the timer before you lie down so you don't oversleep.
• The 20-20-20 rule for your eyes — optometrists recommend that every 20 minutes of screen time, you look at something about 20 feet (6 metres) away for 20 seconds. Run this timer while you work as a reminder.
• A focused work block — twenty minutes is a comfortable step up from 15 and a good entry point to the Pomodoro Method.
• A quick workout — a 20-minute circuit or run is a realistic daily habit.
• Cooking — plenty of pasta bakes, roast vegetables and rice dishes land in the 20-minute range.

Build Up Your Focus

If twenty minutes feels right, try the classic 25 minute Pomodoro next, or drop back to the 15 minute timer on low-energy days.

A Timer You Don't Have to Unlock

For naps and eye breaks, a phone is the wrong tool — it's the thing keeping you awake and staring at a screen. A silent desk timer or a flip-to-start timer cube does the job without the distraction.
