21.67 days per month. There are 52 weeks in the year with 5 working days each = 260 days, and when divided by 12 months = 21.67 days. Weekday holidays are also included. I would say this to be more a accurate calculation: Would it not be correct to say on average there are 365.25 days a year (365 normally 366 every 4th year).
The average month is 365/12 = 30.42 days in a regular year and 366/12 = 30.50 days in a leap year. The Gregorian (western) solar calendar has 365.2425/12 = 30.44 days on the average, varying between 28 and 31 days. The above covers solar months.
