How to use the online alarm clock
As you finish the last jobs and leave the greenhouse, an alarm for 6:22 pm gives you a clear cue to close it before the evening turns colder. It fits the moment when watering, tidying and checking the vents are done, while still leaving 38 minutes before 7:00 pm for locking up and heading home.
With the greenhouse nearly secured, the alarm can remain visible in the browser while you complete the final check outside. The computer needs to stay awake and the page must remain open until 6:22 pm; otherwise the greenhouse reminder will not sound, and the temperature may already be dropping by the time you remember. Keeping the screen active nearby avoids relying on an alert that cannot run after the browser session ends.
Once the greenhouse is shut in the late afternoon, the remaining part of the day is easier to judge if the next commitment already has a little breathing room around it. At 6:22 pm, allow for putting tools away, washing muddy hands and travelling from an allotment or garden before the next evening task. That buffer keeps a small delay at the gate from carrying straight into dinner, collecting someone, or another fixed plan later the same day.
Common questions
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.
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 6:22 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.
