What people set 3 minute timers for

Three minutes is the black tea window: shorter and it is thin, longer and the tannins turn it bitter. It is also one championship boxing round, which is part of why it feels like a natural unit of effort.

Need a different length? The countdown timer takes any duration up to 12 hours, and the pomodoro timer handles work and break cycles for you.

Frequently asked questions

How do I start the 3 minute timer?
The timer loads preset to 3 minutes — press Start (or the Space bar) and it counts down immediately, showing the exact wall-clock time it will finish.
Will it still ring if I switch tabs?
Yes. The deadline is anchored to your system clock rather than counted in ticks, so browser throttling can't delay it. The remaining time also shows in the tab title.
Can I change the duration?
Yes — presets from 1 to 60 minutes are one click away, and the custom field takes anything up to 12 hours.
