How to use the online alarm clock
Waking at 8:07 pm, you have not yet begun checking the river level after the evening downpour. Give yourself a moment to become fully alert, then use the alarm as the point when you get up, find a torch and prepare to look outside. By 9:00 pm, you can be ready without turning the next 53 minutes into a rushed start.
Your river check depends on the alarm page remaining active until 8:07 pm. Set the sound loud enough to hear from where you are resting, keep this page open and leave the phone or computer awake. If the browser is closed or the device falls asleep, the river alarm will not sound, so you could miss the time you meant to make your observation. A separate phone alarm is a sensible backup if you may drift off again.
Before heading out on this wet evening, arrange the light you will need while you are still indoors. Put a charged torch beside your waterproof and test its beam; do not rely on a dim garden light or the glow from your phone. At 8:07 pm, let your eyes adjust before approaching a window, gate or path, and make the observation from a clearly lit, secure position rather than stepping towards a dark riverbank.
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 8:07 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.
