The underlying strptime() Posix system call does not do
a validity check between the month and the day, only that
the month number is [1,12] and the day number is [1,31].  See

If a soldier is asked why he kills people who have done him no harm, or a
terrorist why he kills innocent people with his bombs, they can always
reply that war has been declared, and there are no innocent people in an
enemy country in wartime.  The answer is psychotic, but it is the answer
that humanity has given to every act of aggression in history.  --Northrop Frye
