How to use the online alarm clock
While you wait for the exact moment to put the milk bottles by the door, an alarm for 11:59 pm keeps you from watching the clock every few seconds. It gives you time to gather the bottles and quietly check that the doorstep is clear before 12:00 am arrives.
For this milk-bottle reminder, choose a tone that suits how alert you expect to be. A soft sound may be enough if you are sitting nearby, while a more persistent one is sensible if you might be absorbed in a book or television. Keep the browser alarm running until it sounds; otherwise, the bottles could remain inside after you have stopped thinking about the task.
A late trip to the doorstep is easier when the route is already visible. Before settling down for the evening, leave a hall light on or place a small lamp where it illuminates the door without flooding the room. At 11:59 pm, this avoids fumbling for switches, disturbing anyone who has gone to bed, or stepping into a dark hallway while carrying glass bottles.
Common questions
What happens if my laptop goes to sleep before 11:59 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.
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.
