The algorithm for calculating the date code for a given year is correct; but 
it only returns the date code for January 1st of that year, not any other 
To calculate the date code for any other month, get the date code for Jan 
1st, and then sum up the number of days in each month until the month you 
are looking for, and then take the modulus of 7 and add ddc.

Examples for 2012: ddc = 0
January 2012 has 31 days, to calculate the date code for February 2012 use: 
ddc + 31 % 7 = 3
You will have to account for leap years when doing this.
To calculate July 2012, the process is the same; add all the days until 
July: ddc + 31 + 29 + 31 + 30 + 31 + 30 % 7 = 0

Hope that helps, otherwise the code looks straightforward and like it should
