How to use the online alarm clock
While you wait for the agreed moment to head next door for tea, keeping an eye on 3:17 pm avoids arriving while your neighbours are still getting ready. The alarm can mark the point when waiting becomes leaving, with enough of the afternoon still ahead before 4:00 pm. Allow a little time for shoes, keys and the short walk rather than treating the alarm as the arrival time.
Your departure cue may be quieter than expected if the sound has slipped into connected headphones without you noticing. Before settling down to wait, check where another notification plays and leave the volume at a level you will hear from across the room. Your tea visit needs a separate backup if this page is closed or the phone is allowed to sleep, because the alarm will not sound then. A nearby clock or ordinary phone alarm can cover that possibility.
Leaving for the neighbours during a warm British afternoon can feel abrupt after sitting beside the air conditioning. A few minutes before 3:17 pm, move away from the cool airflow, collect anything you are taking and notice how warm it feels outside. That small transition makes the walk less of a sudden change, especially if the sun is still strong. Light clothing and a glass of water beforehand may also make the short journey more comfortable.
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.
