Method

Time calculation method

The countdown compares the target instant with the browser clock and recalculates the remaining duration four times per second. The target is retained in the page URL for sharing or reopening.

Work hours subtract clock times in minutes, add one day when an overnight shift is selected or implied, then deduct the unpaid break before converting minutes to decimal hours.

Questions

Countdown Timer FAQ

Does the countdown keep running in a closed tab?

No. The displayed timer runs while the page is open, but the target remains in the URL so reopening recalculates the remaining time.

What happens after the target time?

The tool reports that the target has passed and shows elapsed time since that moment.
