Why use a 75-minute timer?
A 75-minute timer is useful when standard intervals (Pomodoro 25, ultradian 90, NASA nap 26) don't quite match your task. Sits between the 60-minute (15 min above) and 90-minute (15 min below) standards.

Frequently asked questions
Why use a 75-minute timer specifically?
75-minute sessions are for extended-focus work, multi-section practice exams, slow-cook recipes, and long meditation retreats. For very long timers, keep the page in the foreground tab — modern browsers may throttle background scripts after extended periods.
Does the 75-minute timer keep accurate time?
For 75-minute intervals, accuracy is typically within 1 second across the full window when the tab stays open. If you minimize the browser for hours, some operating systems aggressively throttle background tabs — keep the tab visible if exact end-time matters for cooking or testing.
Should I keep this timer running for a full 75-minute session?
Yes — keep the tab open and visible for the full 75-minute. Modern browsers throttle background tabs aggressively, especially on battery-powered devices, which can delay the alarm or cause inaccurate end times. Pin the tab if you need to switch away briefly.
What happens when the 75-minute timer reaches zero?
An audible alarm plays and the page flashes a completion indicator. After a 75-minute session, you have probably switched contexts entirely — make sure your device is on a surface where you can hear it, since the alarm is your only return signal.
