How to use the online alarm clock
If evenings tend to slip away in front of a screen, setting an alarm for 7:17 pm gives you a fixed point to stop and do something else. This page rings at 7:17 pm through your device's speakers until you dismiss it.
Set your preferred sound, press Start, then leave the tab where it is. Everything happens inside the browser — no background app, no notification pushed from a server — so an open tab is what actually makes the alarm ring at the right time.
The advantage of a browser alarm is volume and reliability at a desk: laptop speakers are often louder and easier to hear across a room than a phone left in a bag. The catch is that it depends entirely on the tab staying open; if the browser closes or the laptop sleeps, the alarm won't fire. On a 24-hour clock 7:17 pm is written 19:17, and spoken aloud it's seventeen minutes past seven in the evening. Timetables and rosters may show it as 19:17, and handwritten notes as 7.17 pm. Set an alarm for 7:17 pm, set the alarm to 7:17 pm, set my alarm for 7:17 pm — all of it lands on this page and does the same thing.
Common questions
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.
Is this alarm accurate across daylight saving time?
It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.
Can I use this on my phone instead of a laptop?
Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.
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.
