Set an Alarm for 5:00 PM — Free Online Alarm Clock

About waking at 5:00 PM

Five is the end-of-work alarm — worth setting deliberately if you are the kind of person who otherwise looks up at seven. A hard stop is more effective than intending to finish, particularly when working from home.

Leave the tab open

A browser alarm can only ring while its page is open. It does not have to be the tab you are looking at, and on a desktop it does not have to be the window in front — but closing the tab or quitting the browser stops it. For anything you genuinely cannot miss, set a second alarm on your phone as a backup. That is true of every browser-based alarm clock, not just this one.

Common questions

How do I set an alarm for 5:00 PM?

The time is already filled in on this page. Press Add alarm and it arms immediately. Give it a label if you want the alarm to announce what it is for.

Will it ring if my computer goes to sleep?

No. A sleeping device suspends the browser and the alarm fires on wake instead of at the set time. Keep the device awake, or use a phone alarm as a backup.

Does it work on a phone?

Yes, as long as the browser stays open on that page. The screen is kept awake while an alarm is armed.
