This timer draws 5 hours as 20 concentric rings; one empties every 15 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 half-day hike, a wedding reception, or a batch of homemade yogurt.
Five hours is a half-day hike, a wedding reception from the toast to the last dance, and the short end of a batch of homemade yogurt. On the dial each ring is a quarter of an hour, which makes this one of the easiest long dials to read: four rings is an hour, ring ten is two and a half hours, and the last four rings are the final hour.
Five hours of walking at hiking pace, with stops, covers something like fifteen kilometres on rolling ground, and it is about the longest day out that does not need an early start. Set the dial at the trailhead and turn around when it is half dark, at ring ten, unless the route is a loop. The chime is your latest sensible finish, and the rings give a group a shared sense of how far along the day is without anyone asking the time.
Wedding receptions are commonly planned around five hours from the first drink to the end of the dancing. Whoever is running the evening can keep the dial on a phone: speeches done by ring four, the meal by ring ten, the first dance soon after, and the chime a few minutes before the venue's curfew.
Homemade yogurt sets after five to ten hours of incubation, depending on the culture and the warmth of the spot. Five hours gives a mild, loose yogurt; longer is thicker and tangier. Start the dial when the milk goes into the warm place and check at the chime for a set that holds a spoon. For a firmer batch, the 8 hour dial is the usual overnight length.
Because a ring is exactly fifteen minutes, this dial doubles as a schedule for any half-day with quarter-hour slots: a training day of twenty short sessions, a clinic of fifteen-minute appointments, a board game marathon with a round every ring.
A round of golf is the 4 hour dial; a rack of ribs is six hours. Every length the site publishes is listed on the timers page.

A radial timer is a free online countdown timer you set in one click: pick a length, press Start, and an alarm sounds at zero.

No download, no sign-up.
Its dial draws the countdown as 20 concentric rings, one for each twentieth of the duration. Rings empty one by one, outermost first, so a glance shows how far along you are without reading a digit.
Yes. The countdown follows the clock, so it stays on time while you work in another tab and still chimes at zero. The picture-in-picture popout keeps a small dial in view the whole way.
Yes. Any timer exports as an MP4 or a transparent WebM of the whole countdown, up to 4K and 60 fps, in 16:9, vertical, or square.
Yes. In OBS, add a browser source pointing at radialtimers.com/overlay?t=25m and a transparent dial counts down over your scene. Change t for any length, like 90s or 3h.
As many as you need. Each timer gets its own dial and runs on its own, which suits interval workouts, several dishes on the stove, or a room of activity stations.
