	/*
	N.B.: iMonth is zero based, so 0 represents January, 1 represents February, 2 represents March and 11 represents December. iYear is not zero based, this is the actual calendar year number. (2006 is actually 2006)
	 
	To test this function, February in the years 2100, 2005, 2004, 2003, 2001, 2000 and 1999 should be checked. All of these should return 28, except for 2004 and 2000.
	 
	How does this function work? It is quite simple. When the Date() function is given a day number that is greater than the number of days in the given month of the given year, it wraps the date into the next month. The getDate() function returns the day of the month, starting from the beginning of the month that the date is in. So, day 32 of March is considered to be day 1 of April. Subtracting 1 from 32 gives the correct number of days in March!
