About a 12 pm alarm
A midday alarm is useful as a reminder: a lunch break, a medication time or the moment a meeting starts. The UK lunch hour is usually between 12 and 2 pm, and noon is when many schools send children out for lunch, so it also works as a cue to stop a morning task and step away from the screen. Because it falls exactly on the hour, this alarm lines up with the pips on BBC radio and with most train and bus departures, which makes it the easiest time to remember and to coordinate with other people. It is also the time most calendar reminders default to, so it rarely clashes with a meeting that starts on the half hour.
In London the sun is already up at 12 pm in every month. It is still dark, or already dark, at that time in none.
