Countdown Timer

How this tool works

A countdown timer measures a short interval by counting down from a chosen number of seconds. It can help with study blocks, quick breaks, cooking reminders or simple timed activities while you work in the browser.

How to use it

1. Enter the duration in seconds; the initial value is 60.
2. Select Start to begin the countdown.
3. Select Stop to stop the current timer. Start again after entering a new duration if needed.

Example and practical tips

Enter 90 for a one-minute-and-thirty-second interval. The display decreases once per second until it reaches zero.

This is a basic browser timer, not an alarm service. It does not send a notification or guarantee an audible alert. Browser throttling, device sleep or a closed tab may affect timing, so do not rely on it for safety-critical deadlines.

Frequently asked questions

Can I enter minutes directly?

The field is in seconds, so convert minutes to seconds first: 5 minutes is 300 seconds.

Will it alert me when time ends?

The current tool displays the count; it does not provide a separate alarm or notification.
