2008 can be divided by 4 is a leap year, 366 days, the rest of 2005200620072009 are ordinary years, 365 days
365 / 7 = 52 + 1
366 / 7 = 52 + 2
So 2006 New Year's Day is Sunday, 2007 New Year's Day is Monday, 2008 New Year's Day is Wednesday, 2009 New Year's Day is Thursday, 2010 New Year's Day is Friday

9+30+31+30+18=118
118 divided by 7 = 16, more than 6, that is, one day to the next Saturday
