23 Minute Timer

23:00

Press Start and it counts down 23 minutes, turning yellow with 1 minute left and red for the last 15 seconds.

A countdown in your browser

This 23 Minute Timer runs right here in your browser: nothing to install, no account, and nothing sent anywhere. The digits stay readable from across a room, and fullscreen hides everything else, so it works on a classroom projector, a TV or a laptop at the edge of a stage.

23 minutes is a classic slot for a conference talk, a workout or a study session.

How to use it

  • Start begins the countdown and Pause stops it; the space bar does both.
  • Reset puts it back to 23:00 without starting it.
  • Fullscreen, or the F key, fills the screen with the timer. Esc leaves.
  • For another length, type it into the box, such as 7m, 1h30m or 5:00, or pick one from the list below.

FAQ

Can an AI assistant set this up for me?

Yes. Any assistant that can write a link can build you a free MaestroTimer room with this timer: open the link and it is ready in the controller, with a viewer link to put the countdown on a second screen. No account needed.

Does it keep time if I switch tabs?

Yes. The countdown is worked out from when it started, not counted tick by tick, so it shows the right time whenever you look, even after the tab sat in the background.

Can I show it on another screen?

This page runs only on the device it is open on. For a countdown your speaker sees on a stage screen while you control it from your phone, create a free timer room and share its viewer link.
