Because sometimes it may be quite handy to be able to say: the date 20 
months after the day d with just ToDate[FromDate[d + {0,20,0,0,0,0}]].

In fact, this is the behaviour of the mktime function of the standard C 
library (allow any range in the different time fields year, month,etc and 
normalise them in mktime).
