A 45 minute timer for class periods and long focus blocks

Forty-five minutes covers a standard class period, a long deep-work block, or an extended workout. It's a duration where accuracy really counts — over that long a stretch, a browser tab that's been backgrounded or a laptop that's briefly slept is exactly when a naive countdown starts drifting. This one doesn't.

Splitting it into intervals

If you'd rather structure 45 minutes as multiple shorter intervals with breaks in between — for studying or working out — the Pomodoro timer and workout timerpages are built around exactly that pattern.
