How to use the online alarm clock
As you finish watering the allotment greenhouse with collected rainwater, set the alarm for 6:26 pm before packing away the watering can and heading home. It gives you a clear stopping point, so a final check of the beds does not quietly stretch towards 7:00 pm. Keep the phone somewhere clean and dry while you close the water butt, secure the greenhouse door and gather your things.
Water splashing into cans, a running tap and nearby garden machinery can easily cover a quiet signal. Set the browser alarm volume high enough to be heard from the far end of the greenhouse, then test it before starting. This alarm depends on the browser continuing to run; if it stops, the greenhouse finish-time signal will not sound, so use a separate alarm when missing 6:26 pm would disrupt the rest of your evening.
Leaving the plot at 6:26 pm preserves 34 minutes before 7:00 pm, which can absorb the walk to the gate, muddy boots and the journey back without making the next commitment feel rushed. In the late afternoon, decide beforehand which closing jobs are essential: shut vents if needed, return tools and check the latch. Anything non-urgent can wait for the next visit, keeping that buffer intact.
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.
