(Or other once-a-day-and-usually-in-the-same-general-time-window type human activities). So, in my case, I might go to bed at 23:00 one night and then 01:00 the next, so the "naive average" there would be 23 + 1 = 24/2 = 12:00, or noon. But of course, to say I was going to bed around noon would not represent the situation at all. Instead, just as you said, I want in this case 01:00 to be treated as 25:00, so 23 + 25 = 48/2 = 24:00, or midnight. The thing is, other people might have bedtimes at mid-day, if they work nights, for example, so it's hard to know how to approach this. (One visual metaphor I have is to think about the times on an analog clock with hands. For 11pm and 1am, the "average angle" of the big hand is 12:00am.)
