FAQ

Online Countdown Timer questions

?What unit does the countdown timer accept?

The current quick tool accepts the duration as a number of seconds before showing the countdown in minutes and seconds.

?Can I pause the countdown?

Yes. The same control toggles between starting and pausing the countdown, and Reset clears it back to zero.

?Will the countdown keep perfect time in a background tab?

Not necessarily. Browser scheduling can throttle inactive tabs, so use a dedicated timing device for safety-critical or precision timing.
