This timer draws 80 minutes as 20 concentric rings; one empties every 4 minutes, so a glance shows how far along you are without reading a digit. It chimes at zero, keeps counting in a background tab, runs fullscreen, and exports as a free MP4 video. Handy for a rugby match, a college midterm, or simmering a pot of soaked beans.
Eighty minutes is a rugby match, a college midterm, and a pot of soaked beans. It is an hour and twenty, and the dial handles it neatly: each ring is four minutes, so the number of dark rings times four is the minutes gone, and ring ten is the forty-minute mark, which for rugby is half time.
Rugby union plays two halves of forty minutes. For a training match or a club game without a stadium clock, this dial on a phone at the touchline runs the whole match on one face: the first half is the first ten rings, half time is the chime you have to add yourself, and the second half is the remaining ten. If you want a proper chime at half time, run the 40 minute dial twice with the break between.
Many university midterms are scheduled for eighty minutes, which is the standard length of a twice-weekly lecture slot. Practising past papers against the real length is the only way to learn how to pace one. Start the dial as you turn the paper over: four rings to read every question, twelve for answers, four to check. Run it fullscreen beside the paper and it keeps the time without a sound. The exam page is the three-hour version for finals.
Dried beans soaked overnight simmer in sixty to ninety minutes depending on the bean and its age, and eighty is a fair first check for chickpeas or cannellini. Start the dial when the pot reaches a simmer and taste one at the chime; it should be creamy through with the skin intact. Older beans take longer, so restart for twenty if they are still firm.
Seventy-five is the hot yoga class and the whole chicken; ninety is the football match. Both are one step away: the 75 minute and 90 minute dials. Every length the site publishes is on the timers page.
