Frequently Asked Questions
Does it run in background?
Yes. Timer continues in background tabs. You get a notification when it reaches zero.
Multiple timers?
Yes. Create simultaneous countdowns. Each runs independently with its own alert.
Is it accurate?
Accurate to milliseconds for short durations. Minor drift for very long countdowns is auto-corrected.
Does the countdown timer work if I close the browser tab?
Browser-based timers pause when the tab is closed. However, this tool saves the target end time, so when you reopen it, the remaining time is recalculated accurately from the current time.
How do I set a countdown timer for a specific date and time?
Enter the target date and time in the input fields, including the time zone if needed. The timer calculates and displays the remaining days, hours, minutes, and seconds in real time.
