20-Minute Timer

About this 20-minute timer

This is a clean, distraction-free 20-minute countdown. The timer ticks down to zero, plays a clear alarm, and can be reset with a single click. The timer keeps accurate time even if you switch tabs — useful for any kind of background timing.

Common uses for a 20-minute timer

• The TM-style meditation length — also see the 20-minute meditation timer with a halfway chime.
• A NASA-recommended power nap length — long enough to feel restorative, short enough to avoid sleep inertia.
• A short focus block alternative to the 25-minute Pomodoro.
• Reading sessions — long enough for deep engagement, short enough to repeat through a day.
