Questions

Does the countdown make a sound?

No. When the time is up the page shows a Timer done message and puts (Done) in the tab title, so you can see it from another tab. There is no alarm sound.

Does it keep time in a background tab?

Yes. Both are worked out from the clock rather than by counting ticks, so they stay right while the tab is in the background.

Is it saved if I reload the page?

No. The stopwatch and the countdown live in the page and reset when you reload or close it.

What can I type for the countdown?

A number is minutes (5), one colon is minutes and seconds (4:30), and two colons are hours, minutes and seconds (1:05:00).
