About a 10 pm alarm
A 10 pm alarm works as a wind-down reminder before bed, a medication or a screen-off cue. It is a handy bedtime anchor for an early start the next day. 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 10 pm in none. It is still dark, or already dark, at that time in every month.
