About a 11 pm alarm
An 11 pm alarm marks a final lights-out reminder, or a late-evening reminder for shift workers and night owls to prepare for rest. 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 11 pm in none. It is still dark, or already dark, at that time in every month.
