30 Minute Timer

Set aside half an hour for a workout, a cooking task or a focused work session. This 30 minute timer starts with 00:30:00 already selected, so you can press “Start” without entering a duration. Thirty minutes is 1,800 seconds. The large countdown display lets you check how much time remains at a glance.

Use a half-hour block to work through a lesson, make progress on a project or keep track of time while preparing a meal. If your plans change, adjust the hours, minutes and seconds using the columns, the adjustment buttons or the keyboard before starting. Press “Pause” to stop the countdown temporarily and “Resume” to continue from the time left.

“Reset” stops the timer and returns the selection to 30 minutes, including after a countdown with a different duration. When the timer finishes, “Restart” repeats the duration you last used. Enable “Sound” for an audible alert and use “(Check)” to test it. An end message appears when time is up; closing it stops the alert. If automatic audio is blocked, press “Play sound” in the message.

Your running or paused countdown is restored after a reload in the same browser when browser storage is available. This page saves its state separately from the other timer pages, so their countdowns do not change when you use the 30 minute timer. Keep the page open for the end notification. Sound may be delayed while your device is asleep or the browser suspends the tab.
