One possible approach is that... 31 days can be expressed as 28 days +3 days... and now 28 days = 4X7...i.e all days in week... remaining there are 3 days....this cannot be of the combination... sat-sun-mon,wed-thu-fri...the only possible way is mon-tues-wednesday...so month starts from monday....

monday
start day of any month will end at that day,so month cannot start with sun or thurs,
monday because end will be at monday which is on 29 and remaing 2 days will be tue and wed.
so sun=4 and thurs=4 is maintained
