[math-fun] Most valuable moments

Hello Math-Fun, say we could append a value to every moment of our life during a year; we would simply add the digits of the date (month and day) to the digits of a precise time (hours, minutes, seconds). For example, the second before 2020 would be worth (1+2) + (3+1) + (2+3+5+9) = 3+4+19 = 26. What moment of the year has the highest value? What is the most common value in a year? (midnight on the first of January = 2 = mid- night on October 10th) How many moments are prime in a year? Best, É. (sent at moment 27, Brussels time = 31 XII 19:55)
