Frequently Asked Questions — Countdown Timer
Does this timer work in the background?+
The timer uses setInterval and will continue running as long as the browser tab is open. Switching tabs may slow it slightly on some browsers.
Is there an alarm when it finishes?+
Yes, a brief audio cue plays when the countdown reaches zero. Due to browser restrictions, the tab must be active for audio to play.
