Question received from a 14yr old pupil: If it takes 28 days for the moon 
to orbit the earth, why do the length of calender months vary from 28 to 
31? Also if there are 12 months (or 12 orbits of the earth by the moon)in 
a year why is not a year 336 days (i.e 12 x 28. The earth orbits the sun 
once in 365.25 days - so why are there inconsistencies in the length of 
months?
