Turning this on asks your browser for permission once.

Paste that anywhere HTML is allowed. Free to use, no attribution required.

The countdown is anchored to a finish time, so it stays exact even if the tab is in the background. Press Test sound once so the browser lets audio play. Space starts and pauses, L takes a lap, R resets.

Twelve minutes is the length of the Cooper running test, and a comfortable block for a language drill or a set of practice problems.

If you want two things timed at once, set this one running and press Add another timer to stack a second countdown underneath it.

A free online timer, stopwatch and countdown clock that runs entirely in your browser. No account, nothing to install.

It keeps working offline once loaded, and you can add it to your home screen like an app. Your settings stay in your own browser.

Press Voice control and allow microphone access, then speak normally. Your speech is handled by your browser's own speech service, and nothing is stored by this page. Allow the microphone once and switch this on once, and it stays on as you move around the whole site, in this tab or a new one. It switches itself off after an hour of not being used. The button always shows whether it is listening, and tapping it stops it for good.

What is the Cooper test?

A twelve minute run covering as much distance as you can, used as a rough measure of aerobic fitness. Start the timer as you start running, not as you line up.

How many seconds is twelve minutes?

Seven hundred and twenty.

Can I run a second timer alongside this one?

Yes. Press Add another timer and the two count down independently, each with its own label and finish time.
