Some months have 31 days due to the historical development of the Gregorian calendar, which is based on the Roman calendar. Initially, the Roman calendar had months of varying lengths, and Julius Caesar reformed it to include 30 and 31-day months, leading to the current structure. The distribution of days was influenced by political and social factors, with some months receiving extra days to honor certain deities or leaders. As a result, January, March, May, July, August, October, and December each have 31 days.
