About this timer
An hour and a half (1 hour 30 minutes): roughly one full sleep cycle, which is why it's a popular length for a longer nap. It's also the regulation length of a soccer match and of many exam papers. Keep your device plugged in so it doesn't sleep first.
Timers this long are set once and forgotten: baking and braising, parking meters, long study or work blocks, and charging cycles. Because the countdown is anchored to a real clock time, it stays accurate for hours in a background tab, and it survives a page refresh.
Need a different length? Set a custom timer in hours, minutes and seconds, or pick one of the presets below.
