How to use the online alarm clock
Finish what you are doing and get ready to leave for the neighbourhood patrol when the alarm sounds at 9:34 pm. That gives you a clear departure point without repeatedly checking the clock, while still leaving time to collect your keys, torch and reflective layer before 10:00 pm.
For a patrol departure, choose the alarm tone according to what is happening around you. A softer sound suits a quiet room when you are already preparing to go, while a more persistent tone is sensible if conversation, television or household noise might mask the first alert. Set the volume so it is noticeable without startling anyone nearby. Keep the browser alarm active and the screen awake; if the browser is shut or the system sleeps, your patrol departure may pass without a sound.
Stepping outside for an evening patrol can feel surprisingly warm after sitting near air conditioning. Before leaving at 9:34 pm, spend a moment away from the cool airflow, check the temperature outdoors and take water if the evening remains hot. A light, breathable layer is easier to adjust during the walk than clothing chosen for the chilled indoor air, especially as the patrol continues towards 10:00 pm.
Common questions
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 9:34 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.
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
