How to use the online alarm clock
Pack your music, check the route and set the alarm while there is still time to prepare for the mining town’s brass-band rehearsal. A 4:59 pm alert gives you a clear cue to stop sorting your things and get moving, with 5:00 pm arriving a minute later rather than becoming an unnoticed deadline.
The rehearsal may be noisy later, but the alert itself can disappear into headphones before you leave home. Check where your phone or computer is sending audio, especially if wireless headphones were used earlier and are now lying in a bag. The alarm also depends on the browser remaining active and the phone or laptop staying awake: if the page is closed or the device sleeps, no sound will play, which could leave you late for the brass-band rehearsal.
If 4:59 pm is meant to end an afternoon nap before rehearsal, place the screen beyond easy reach and leave your music, coat and keys together. That small bit of preparation makes it less tempting to silence the alert and drift back to sleep. If you plan to sleep again later, keep the evening routine separate so this one-minute warning before 5:00 pm does only one job: getting you ready to leave.
Common questions
Can I use this on a phone?
It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
Does the alarm still work if I close the tab?
No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
What happens if my laptop goes to sleep before 4:59 pm?
The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
