Using the 40 Seconds Timer

This timer is already set to 40 seconds. Press Start Timer when you are ready, keep the browser tab open, and use the sound selector or full-screen view if you need a clearer alert.

40 Seconds sits in the short burst range - about 1.1% of an hour, and 90 of them fit inside an hour. That length suits a quick tidy-up sprint, a quick stovetop task, or a set of push-ups, so pick one job before you press Start and let the countdown protect it. When you need a few of these running side by side, the multi-timer keeps them all on one screen.

A timer measures a length, not a clock time. If what you really want is an alert at a set moment - a meeting, a wake-up, a pickup - an online alarm is the better fit, and you can keep both open at once. For anything you would rather measure going up instead of down, like laps or how long a chore actually takes, switch to the stopwatch.

Precisely, 40 Seconds is 40 seconds (40 seconds). The countdown runs in this browser tab, so keeping the tab open and the device awake is what lets it ring on time - give longer timers a quick sound check before you step away.

If the task needs setup, spend no more than 10 seconds preparing before the real work begins.
At the halfway mark, ask whether the goal still fits inside the remaining 20 seconds.

When this duration is not ideal
