How to use the online alarm clock
Waking at 3:38 pm gives you a clear cue to get up and prepare to hand the church-hall keys back to the caretaker. Set the alarm for that exact time, then leave enough room to dress, check that you have the right keyring and arrange the handover before 4:00 pm. Keeping the keys beside your phone can prevent a sleepy search as you leave.
Your handover depends on the alarm still being able to sound after you have drifted off again. Keep the alarm page running and prevent the phone or computer from sleeping until 3:38 pm. The church-hall keys could remain with you if the page is dismissed or the phone falls asleep before the alert. For a more dependable prompt, leave the charger connected, turn the sound up and check that silent mode will not suppress the alarm.
Stepping outside soon after an afternoon sleep can feel different from the room you woke in, especially when the air is damp. Before setting off with the keys, check the local humidity and conditions, then choose a light layer that will not become uncomfortable on the walk. If the air feels close, allow an unhurried minute by the doorway before heading to the hall; if rain is hanging around, keep the keyring in a secure, dry pocket.
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 3:38 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.
