About this 9-minute timer
A one-click 9-minute countdown, most often used for a snooze-style nap, hard-boiled eggs, or a short workout. It runs in your browser and rings when it reaches zero.
Nine minutes: the snooze length
Nine minutes is the classic snooze interval on many alarm clocks. A common explanation is that early mechanical clocks could only count to nine minutes and fifty-nine seconds with their gears; whatever the origin, it stuck. It's also a common time for fully hard-boiled eggs.
