This document contains code that counts the number of Fridays that fall on the 13th day of each month between the current date and December 31st, 2013. The code initializes a Calendar object for the end date of December 31st, 2013. It then initializes a second Calendar for the current date and sets it to the 13th day of the month if needed. A while loop runs from the current date to the end date, adding any dates that fall on a Friday to a List, incrementing the month each iteration.
