Countdown Timer

Timer counts down a set time: tap a preset to start at once, or type hours, minutes and seconds and press Start (or Enter). Space starts and pauses when you are not typing. Plus 1 min adds a minute to the run in progress; Reset puts it back to the time you set. With Repeat timer on, it starts again by itself each time it reaches zero.

Event counts down to a date and time you choose and shows the days, hours, minutes and seconds left. The nearest one to come is shown unless you pick another from the list; once it has passed it counts up instead. Days are counted on the calendar, so a clock change does not add or lose an hour in the count.

The timer keeps the moment it ends, not a running tally, so it stays exact in a background tab, on a sleeping phone and after a reload. At zero you hear a short chime made by your browser (no audio file), the phone vibrates where it can, and a notification appears if you turned Notifications on. Everything is saved on this device only.
