The calendarepoch for the gregorian calendar (that the western world has been used since the 16th century) is 400 years. After that, the whole calendar repeats itself. It is exactly 146097 days in these 400 years. (Yes. including all 4/100/400-rules.) Distributed among these 146097 days - there are 28 days that is more frequently occuring than the others, 688 times each in 400 years. These are to be found in the first group of the table below. Note that, friday the 13th is among them. On the other hand - there are 27 days that are as common, and the next group of 56 days are only a little less frequent. More funny worthless knowledge is that Wednesday the 31th is the least common date+day-combination.
