How to use the online alarm clock
As you hand over the job of securing the henhouse, set the alarm for 9:12 pm and tell the next person exactly which latch needs checking. That leaves enough evening for them to act before 10:00 pm, rather than discovering later that urban foxes had an easy way in. A clear handover also prevents each person assuming the other has already dealt with it.
Because this reminder marks a practical responsibility, test the sound now, while the person taking over is still nearby. Set a temporary alarm a minute ahead, raise the volume to a level they can hear, and confirm which sound will play. Closing the page or allowing the phone to sleep can silence the henhouse reminder, so whoever is responsible should keep it active until 9:12 pm and use a separate alarm if that cannot be guaranteed.
When one person is heading outside at 9:12 pm, warn anyone else in the house before the alert sounds, especially if children are settling down or someone is watching television nearby. Keep a torch and the key by the back door so the check is brief, and agree whether the person indoors should listen for the gate closing or wait for a quick spoken confirmation that the hens are secure.
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 9:12 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.
