About this tool
This page opens the countdown timer already set to 5 minutes — press start and the clock is running.
Five minutes is the classic short burst: steeping tea, a quick stretch between tasks, soft-boiled eggs, or giving kids a fair turn on the tablet.
Need a different length? The full timer takes any minutes and seconds, has pause and reset, and keeps counting in your browser tab even offline.
Example. The form opens at 5 minutes and 0 seconds and displays 05:00. Start runs until 00:00, then the status reads Time is up. and a sine at 880 Hz plays for 0.35 seconds. A zero duration does not start.
Limit. There is no hour field, so 90 minutes display as 90:00. Seconds are clamped to 0–59. A hidden tab jumps to the deadline instead of ticking in the background. The tone does not repeat.
