How to use the online alarm clock
You are finishing up and heading indoors after securing the henhouse against urban foxes, so an alarm for 11:32 pm gives that final check a definite end point. The 28 minutes before 12:00 am leave enough time to fasten the latch, look along the fence and put away anything left in the garden without drifting into another late task.
While you move between the run and the back door, the alarm can continue counting in a browser tab that sits behind another page. Returning to that tab should still show the set time, provided the browser remains open and the phone or computer stays awake. If you close the page or allow the device to sleep, no signal can sound, and the henhouse check may be missed. Keeping the alarm visible during the last few minutes makes its status easier to confirm.
Once the hens are shut in, pause near the gate and listen before going inside. Traffic, neighbours and garden activity are usually quieter by 11:32 pm, so a scraping panel or movement beside the run may stand out more clearly. Set a tone that is audible from the garden but not needlessly loud indoors, and keep the phone out of a coat pocket where fabric could muffle it.
Common questions
What happens if my laptop goes to sleep before 11:32 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.
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.
