Online alarm clock for 7:35 pm
While you wait to leave for the neighbourhood patrol, set the alarm for 7:35 pm and keep an eye on the time without repeatedly checking the clock. The alert gives you a clear cue to collect your torch, keys and reflective layer before stepping outside. With 8:00 pm still ahead, you can meet the others at the agreed point without treating the round hour as your departure time.
Your patrol reminder depends on the phone, tablet or computer staying awake until the alarm sounds. If the screen is likely to sleep first, adjust its power settings temporarily or keep the device active nearby. A closed browser or sleeping device cannot sound the patrol alarm, so use a separate alarm clock or phone alarm if you may put it away before 7:35 pm. Set the volume high enough to hear, then leave the page open.
As your patrol departure approaches, notice which evening sounds could mask the alert: television from another room, traffic at the front of the house, or conversation near the door. By 7:35 pm, commuter noise may be easing while household noise continues. Keep the alarm beside you rather than under clothing or inside a bag, and choose a tone that stands apart from the surrounding sounds.
Common questions
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.
Will it still be right when the clocks change?
Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
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.
