Countdown Timer
Set a duration in hours, minutes and seconds and count down to zero — with one-tap presets including a Pomodoro.
Set any duration in hours, minutes and seconds, hit start, and this timer counts down to zero on screen. Quick-preset buttons load common lengths in one tap — 5 minutes, a 25-minute Pomodoro, 1 hour and 2 hours — and you can pause or reset at any point. It runs entirely in your browser, with no account and nothing to install.
The 25-minute Pomodoro preset
The 25 Min (Pomodoro) preset exists because of a popular focus method: you work in a single 25-minute block on one task with no interruptions, then take a short break, and repeat. The fixed, visible countdown is the whole point — a shrinking timer creates gentle urgency and gives you permission to ignore everything else until it hits zero. Pair it with the 5-minute preset for the breaks in between.
Keep the tab open while it runs
The timer is driven by your browser, so it only counts while the page is open. Most browsers also throttle timers in background tabs to save power, which can make a hidden countdown update less smoothly. For an accurate run, leave this tab visible. Reset clears the clock back to your set time; pause freezes it so you can resume exactly where you left off.
Frequently Asked Questions
What does the Pomodoro preset do?
It loads 25 minutes — one focused work block in the Pomodoro technique. Work the whole block on a single task, then take a short break (the 5-minute preset is handy for that).
Will it keep counting if I switch tabs or close the page?
It keeps counting while the tab is open, but browsers throttle timers in hidden tabs so a background countdown may update unevenly. Closing the page stops it entirely.
Can I pause and resume?
Yes. Pause freezes the countdown where it is; pressing start again resumes from that point. Reset returns the clock to the duration you set.
Do I need to install anything or sign in?
No. It runs in your browser with no account and no download.
