How Can I Set an Alarm on a Computer?

You can simply use our free online alarm clock right here. No download is required. Just choose your desired time and set the alarm. Keep the browser tab open, and it works on any computer with an internet connection.

If you'd like to use your computer's native alarm clock to set an alarm:

  • You can set alarm clocks on a Windows 11 computer using the Clock app. You can also use this application to set a timer or start a stopwatch.
  • On a MacBook, you can use the Calendar app. For a more advanced solution, you need to download an alarm app to set alarms.

What Is the Online Alarm Clock?

The online alarm clock is a digital alarm clock you can use for free via your internet browser on any computer or mobile device. You can use the alarm to wake up in the morning and to help with daily routines like studying, exercising, cooking, or completing practice exams.

How Can I Set an Online Alarm?

Using this alarm clock is simple. All you need to do is:

  • As a first step, set a specific time you want the alarm to go off in Hours and Minutes, or use the pre-selected alarm times. Don't forget to check the current time before setting the alarm time.
  • Pick your Alarm sound from the list by clicking the arrow and then clicking your preferred alarm sound. (optional)
  • Give your alarm a title under Alarm name. This will be your alarm message or a reminder that appears on the screen when you start the countdown (optional)
  • Click Set an alarm to set the alarm clock.
  • To set multiple alarms, open another tab and repeat the steps.

Once you set the alarm, a live countdown will appear on-screen. When the countdown reaches zero, an alert will sound. You can end the active alarm by clicking "Stop" or click the "Snooze" button to delay it for 10 minutes. Note that the tab must remain open for the alarm to function, though it doesn't need to be the active tab.

Additionally, you can view alarms you've previously set under Alarm Clock Data. Click Export to CSV to download the saved alarms or Clear Data to delete the history.

The alarm clock remembers your latest settings, like the specified time or alarm label. Before setting a new alarm, you can see these saved settings and either use them or change them as needed.

Is This a Loud Alarm Clock?

Will the Online Alarm Clock Work If I Close the Tab?

Does the Online Alarm Clock Work When the Computer Is in Sleep Mode?

No, the alarm will not work if your computer is in sleep mode. However, the alarm will still function if only your display is turned off (screen is dark). If you're unsure whether your system keeps the alarm active with the display off, test it beforehand or keep your display on to be safe.

Does the Online Alarm Clock Work When the Computer Is Shut Down?
