How to use this 150 minute timer

Get started in four simple steps.

  1. Choose your sound

    Pick one of seven alarm sounds or Off, and use Test sound to check the volume.

  2. Start

    Press Start timer when you are ready – the display starts at 02:30:00. Opening this page never starts the countdown by itself.

  3. Pause when needed

    Pause and resume at any time. Reset restores the full 150 minutes.

    At zero – 150 minutes after you pressed Start, not counting pauses – the page shows Time’s up and tries to play your alarm for up to 10 seconds, then keeps counting how long ago it finished.

150 minutes is 9,000 seconds, or 2 hours 30 minutes. For timers of several hours, keep the device plugged in and the page open. A browser may pause pages on a sleeping device, so a separate alarm clock is more dependable for very long waits.

What time will it be in 150 minutes?

If you start now, the timer ends at 5:30 PM.

The time above is read from your device clock and updates every second (without JavaScript it shows an example start of 3:00 PM). For other spans, use the time from now calculator, the hours to days converter or the page for 48 hours from now.

Frequently asked questions

Still have a question? Get in touch

How many seconds are in 150 minutes?

150 minutes is 9,000 seconds, or 2 hours 30 minutes. The timer shows it as 02:30:00 when it is ready to start.

Can I pause the 150 minute timer?

Yes. Pause holds the remaining time and Resume continues from there. Reset returns to the full 150 minutes, and asks first while the timer is running.

How do I set a timer for 150 minutes?

This online timer is already set: open the page and press Start timer, and the 150-minute countdown begins at 02:30:00. Nothing to install, and no sign-up. It is the same countdown people look for as a 150 min timer, 2 hour 30 minute timer or 2.5 hour timer.

Is a 150 minute timer the same as a 2 hour 30 minute timer?

Yes. 150 minutes is 9,000 seconds, or 2 hours 30 minutes. You may also see it written as a 2.5 hour timer. Use this page for either; the countdown is identical.

Is this the same as the Google timer for 150 minutes?

No. Typing “timer 150 minutes” into Google shows Google’s own built-in timer. MinuteTimer is an independent website with no connection to Google. Use this page for a 150-minute countdown with a choice of alarm sounds, a full screen view and a page you can bookmark.

Will the alarm work if I leave this tab?

Keep the tab open. Switching to another tab is usually fine, but browsers can slow down pages in the background and may block sound that was never enabled. For the best chance of hearing the alarm, keep this page open and visible and press Test sound first. Closing the tab stops the alarm.

Reset this timer?

The countdown will stop.
