How to use the online alarm clock
Study sessions, evening training, or a reminder to log off before the night gets away from you: 9:04 pm works well as an evening checkpoint. This rings straight from your browser at 9:04 pm, and keeps ringing until you stop it. No app required.
Select a sound, hit Start, and that's the whole setup. The countdown runs inside this browser tab rather than on your device's operating system, so it needs to remain open, on a phone or laptop, until the alarm actually goes off.
Compared to a phone, this alarm has one job and nothing else competing for attention — no messages, no app switching. It's free and doesn't ask for sign-up, but it only works while the tab is open and the device stays awake, so it suits daytime use at a desk better than an overnight bedroom alarm. On a 24-hour clock 9:04 pm is written 21:04, and spoken aloud it's four minutes past nine at night. Timetables and rosters may show it as 21:04, and handwritten notes as 9.04 pm. Set an alarm for 9:04 pm, set the alarm to 9:04 pm, set my alarm for 9:04 pm — all of it lands on this page and does the same thing.
Common questions
Can I set more than one alarm at a time?
This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.
Why use a browser alarm instead of my phone's built-in one?
Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.
Is there a cost to use this?
No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
Will the alarm still ring if I close the browser tab?
No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.
