Any month with 30 or 31 days can have 5 weekends (Sat-Sun) if it starts on a Saturday - for 30 day months - or a Friday or Saturday - for 31 day months. Months with only 4 weekends are any February, or any month that does not start on a Friday or Saturday. A non-leap year calendar year will have either 52 or 53 weekends, and will have either 2 or 3 months with 5-day weekends.
