How to use the online alarm clock

Midday shifts, split rosters, and long lunch breaks all make 1:31 pm a useful checkpoint. Choose a sound, set this for 1:31 pm, and leave the tab open. It'll ring right through your laptop speakers whether you're at a desk or on the couch during a break.

Choose a sound before you press Start — something like a chime or a classic bell tends to work better than anything too gentle. Once it's running, the countdown happens right here in the browser, which means the tab needs to stay open in the background rather than being closed.

Some people use this alongside a phone alarm rather than instead of it: a louder backup through laptop speakers, or a way to set a reminder without touching a phone at all. It won't survive the tab closing or the device sleeping, so for anything critical overnight, keep a second alarm running as well. On a 24-hour clock 1:31 pm is written 13:31, and spoken aloud it's twenty-nine minutes to two in the afternoon. Timetables and rosters may show it as 13:31, and handwritten notes as 1.31 pm. Set an alarm for 1:31 pm, set the alarm to 1:31 pm, set my alarm for 1:31 pm — all of it lands on this page and does the same thing.

Common questions

Does the alarm work if my laptop goes to sleep?

Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.

Do I need to create an account or download anything?

No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.

Can I change the alarm sound?

Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.

What happens once the alarm goes off?

It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
