About a 9 pm alarm
A 9 pm alarm is a useful wind-down prompt before bed, with the news at 10 pm and an early start in mind. Many people use it as a cue to stop work and begin an evening routine. 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 9 pm in June and July. It is still dark, or already dark, at that time in January, February, March, April, May, August, September, October, November and December.
