About a 4:30 pm alarm
A 4 pm alarm is a useful end-of-afternoon prompt: a school pick-up for older children, a tea break, or a reminder to prepare for the end of the working day. In midwinter the sun sets around this time. A half-past time is popular because it splits the hour neatly, leaving a relaxed gap before anything that starts on the hour. It works well if you want a short walk, a shower or a coffee before leaving, and it is a common choice for people on flexible or hybrid working patterns.
In London the sun is already up at 4:30 pm in February, March, April, May, June, July, August, September and October. It is still dark, or already dark, at that time in January, November and December.
