Online alarm clock for 4:04 pm
As you hand the greenhouse watering over to someone else, set the alarm for 4:04 pm so they know exactly when to use the collected rainwater. That leaves a clear marker in the afternoon rather than a vague instruction to do it later, with enough time afterwards to finish the job and put everything away before 5:00 pm.
Because the watering is now in someone else’s hands, check that the alarm can remain active on the phone or computer they will actually hear. Keep the browser running and prevent that device from sleeping beforehand. If it powers down or the page is closed, the alarm will not sound, and the greenhouse may miss its planned rainwater session. Setting the volume and leaving the screen nearby makes the handover less dependent on another reminder.
Once the greenhouse watering has been covered, treat 4:04 pm as a firm end to your responsibility for the afternoon. If you expect to sleep after this point, avoid leaving another check hanging over you: ask the other person to confirm when the rainwater has been used. That small piece of closure can stop the unfinished task from following you into the rest you have set aside.
Common questions
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.
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.
