How to use the online alarm clock
Before handing over for the evening, tell the next person that the milk bottles need putting by the door and set the alarm for 8:18 pm. That leaves a clear reminder well before 9:00 pm, so the job is less likely to be lost between changing shifts, finishing the washing-up or settling down for the night.
Because someone else will act on the reminder, match the alarm sound to where they will be. A soft tone may suit a quiet sitting room when the phone is nearby; a more insistent one makes sense if they will be moving between rooms or listening to the television. Check the volume before leaving them responsible for it. The alarm will not sound if the browser is no longer running or the phone has gone to sleep, which could leave the milk bottles indoors, so keep the page active and use a separate backup if nobody will be watching the screen.
Once the bottles are outside at 8:18 pm, note whatever comes next that evening rather than treating the reminder as the final task. With 42 minutes until 9:00 pm, there is room to finish one defined job, such as clearing the kitchen, while keeping a small buffer for locking up and checking the doorstep before bed.
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 8:18 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.
