35 Minute Timer

A 35 minute working session - about as long as most people can hold real concentration before the returns start dropping. Fullscreen it on a second monitor and forget the clock until it blinks.

What it is good for

Frequently asked questions

How do I set a 35 minute timer?

Open this page and press Start, or hit the space bar - the countdown is already loaded with 35 minutes. Press F for fullscreen if you want to read it from across the room, and use the custom field to switch to any other duration.

Does the timer keep running if I switch tabs?

Yes. The countdown is calculated from a fixed end time rather than counted tick by tick, so background throttling cannot make it drift. The remaining time also appears in the browser tab title while you work in another tab.

Does it make a sound when the time is up?

Yes, it chimes three times and the clock turns red. The last ten seconds blink as a warning, and the chime can be muted with the speaker button.

Is this timer free?

Yes, it is completely free, needs no account, and runs entirely in your browser - nothing is sent to a server.
