How to use the online alarm clock
Break away from the job in hand at 8:14 pm and secure the henhouse before urban foxes begin exploring the garden. Setting the alarm for this precise moment means the task does not drift towards 9:00 pm while you finish washing up, answer messages or settle in front of the television.
Your reminder for the henhouse needs to be heard beyond whatever you are doing indoors. Before leaving the alarm running, check where its sound is being sent: wireless headphones may still be connected even after you have put them down, leaving the room itself silent. Play a brief test sound and disconnect the headphones if the alert should come through the phone or computer speakers. A browser alarm cannot sound once it has stopped running, so the henhouse may remain unsecured if this is your only reminder.
Closing up is easier when you notice how the evening soundscape changes around 8:14 pm. Traffic, neighbours and garden activity can mask scratching or movement near a fence, then fade unexpectedly as 9:00 pm approaches. Pause at the back door for a few seconds before walking out, listen near the run, and use a torch to check quiet corners rather than judging solely by what you can hear from indoors.
Common questions
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.
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.
