15 minute timer — free online countdown

A 15 minute timer counts down from 15:00 to zero and rings a loud alarm. Press Start or the Space bar to begin — no download, no sign-up, and the countdown stays accurate if you switch tabs.

Fifteen minutes is the most useful block on the clock: long enough to finish something real, short enough that you'll actually start. This free online 15 minute timer opens preloaded, starts on one click, and loops the alarm until you dismiss it so it can't be missed from another room.

What people use a 15 minute timer for

Use	Why 15 minutes works
Daily stand-up meeting	The standard agile stand-up box — long enough for a small team, short enough to stay standing.
Quick tidy or reset	One room, one surface. The classic "15 minute tidy" beats an open-ended clean-up you never begin.
Study warm-up	Half a Pomodoro. Good for flashcards or a reading pass before committing to a longer block.
Workout circuit	Three to five rounds of bodyweight work, or a full express session on a busy day.
Oven and kitchen steps	Roasting vegetables, proving a quick dough, resting a joint of meat.
Power nap wind-down	Fifteen minutes keeps you in light sleep, so you wake without the grogginess of a longer nap.

How to run a 15 minute block that actually works

Decide the single outcome before you press Start — "clear the inbox", not "do email". Put the phone face down, let the timer own the clock, and stop when the alarm rings even if you're mid-flow; finishing on time is what makes you willing to start again tomorrow. If you want to keep going, press +5 min rather than restarting from scratch, so the total stays honest in your stats.

Nearby durations

If 15 feels tight, the 20 minute timer adds one more pass without breaking your afternoon; if it feels long, 10 minutes is the lowest-friction way to start. For repeated work/break cycles use the Pomodoro timer, which chains 25 minute focus blocks with 5 minute breaks automatically.

Frequently asked questions

How do I set a 15 minute timer online?

Open this page and press Start (or the Space bar). The 15 minute countdown begins instantly and a loud alarm loops when it reaches zero. There is nothing to install and no sign-up.

What time will a 15 minute timer finish?

Fifteen minutes from the moment you press Start. The page shows the exact finish time in your local clock above the countdown, so you can check it before you begin.

Is 15 minutes a good length for focused work?

Yes. Fifteen minutes is short enough to start when you're procrastinating and long enough to get into a task. It's the standard length for a stand-up meeting, a quick tidy, a workout circuit, and one round of exam revision.

Does the timer keep running if I switch tabs or lock my phone?

Yes — the countdown is anchored to a real end-timestamp rather than a tick counter, so a background tab stays accurate to the millisecond. On phones, add Tickline to your home screen and allow notifications so the alert still fires when the browser is closed.

Can I share this exact timer with someone?

Press Copy link and send the URL. Whoever opens it gets the same 15 minute timer preloaded and ready to start.

How do I make it louder or silent?

Pick a different alarm sound in the controls under the countdown. There's a loud bell for noisy kitchens and gyms, and a silent mode that flashes the screen red instead of playing anything.
