About this timer
A full class period at many high schools and colleges, and a common length for one section of an exam. For work, 55 minutes on and 5 off keeps you on the hour, so the next block starts at a round time.
Close to an hour without committing to one, which suits deep work sessions, laundry cycles, exam practice, and slow cooking. Leave the tab in the background and the alarm will still fire at the right moment, because the countdown is anchored to a clock time rather than to a ticking counter.
Need a different length? Set a custom timer in hours, minutes and seconds, or pick one of the presets below.
