Two dates of ‘DateTime’ type is defined and an array of days of a week is defined, where initially the count of all days of a week are 0. The dates are converted to a time format and timestamp variable is assigned to it. An array named ‘week_day’ is incremented and increments the days of the week based on how many times it has been encountered during the iteration.
