/*
Note that getYear() function returns years in two digits for year between 1900 to 1999 and it returns three digit year starting from year 2000. So for the year 2000 getYear() function will return 100 and for 2001 it will return 101. For the year 2006 it will return 106. Same way for the year less than 1900 it will return negative number starting from -1 for the year 1899 and 0 for the year 1900. 
getFullYear() function returns year in 4 digits for all the years. So it is better to use getFullYear() function than getYear function.
