A 15-minute block without a kitchen gadget
Phone clocks bury the countdown under other apps. This page stays on a spare monitor or a shared classroom display. For a full class period, try the 45 minute timer instead.

Fifteen-minute countdown
A quarter-hour timer, already set
This landing opens at 15:00. Use it for a short meeting buffer, a language lesson, a walk, or a homework sprint. Press Start; the rest of the timer (looks, sleep, embed) is the full tool.
Fifteen minutes is long enough for a real attempt and short enough to stay honest. Teachers use it for stations; remote teams use it to cap a stand-up. The alarm is local to your browser so nobody else is interrupted.

01
Start at 15:00
Hit Start to begin fifteen minutes. Tap the dial only if you need a custom 15:30 or similar; otherwise leave it and go.
-
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.
Can I show a 15 minute timer fullscreen for a class?
Yes. Use fullscreen or display mode so the digits fill the screen. Sleep mode dims chrome so only the countdown stays visible.
Does the 15 minute timer work offline after the page loads?
Once loaded, the countdown runs in the browser. A flaky network will not stop a timer that already started. First visit still needs the page to load.
How do I share a 15 minute timer link?
Copy the page URL, or use Share on the stage to copy a link that includes look and duration. Recipients land on the same 15:00 preset.
Is 15 minutes the same as a Pomodoro?
No. Classic Pomodoro is 25 minutes of work plus a short break. Use this page for a 15-minute burst, or open the Pomodoro timer on the home page for 25/5 cycles and stats.
