How to use the countdown timer
Set a focused duration in minutes and seconds, then pause, resume or reset the countdown in the current browser tab.
Formula or method
The entered duration is converted to total seconds and reduced once per second until it reaches zero.
Worked examples
Twenty-five-minute focus block
Enter 25 minutes and 0 seconds for a simple focused-work interval.
Short kitchen reminder
Enter 1 minute and 30 seconds for a 90-second countdown.
Pause without resetting
Pause midway through a timer and resume from the remaining time instead of starting over.
Frequently asked questions
Can I pause and resume the countdown?
Yes. Pause keeps the remaining duration, and Start resumes from that point.
Will the timer make a sound?
The current timer emphasizes an on-screen completion state; browser audio permissions and device settings are not required.
Does it continue in a background tab?
It uses elapsed clock time, but browsers can delay screen updates when a tab or device is suspended.
What happens when I refresh the page?
The timer resets because its state is kept only in the current page session.
Limitations
Browser power saving or a suspended tab can delay on-screen updates.
