2 Minute Timer
A ready-to-go 02:00 countdown -- press Start, or set a different duration below if you need one.
Keyboard: Space start/pause, R reset, Esc stop alarm.
What a 2 minute timer is used for
- the two minutes dentists and dental associations recommend for brushing your teeth
- the "two-minute warning" before the end of each half in American football
- a fast round of instant noodles' minimum cook time on many packages
- a short cold-shower or ice-bath interval in some cold-exposure routines
- a two-minute elevator pitch with time left over for questions
Why 2 minutes
Two minutes is a genuinely useful default because it matches a real, widely cited recommendation: dental associations recommend brushing for two minutes, twice a day, and most people brush for well under a minute without a timer running. It's long enough to notice passing, short enough that almost nothing feels like a burden for it.
2 minutes = 120 seconds = 1/30 hour
How it stays accurate
Like every timer on this site, this one never counts down by subtracting one second at a time -- it records the exact target end timestamp the moment you press Start, then recomputes the time left from that fixed target on every screen update. Switching tabs, minimizing the window, or letting the browser throttle a background tab doesn't cost any accuracy, because the next update still does the subtraction fresh rather than trying to catch up on missed ticks. The alarm itself is synthesized with the Web Audio API -- no audio file, nothing an ad blocker could interfere with -- and repeats until you stop it with the Escape key, the Stop alarm button, or by starting a new countdown.
