that and the calendar of 2005 is the same as that of 1994 (safe for some holidays)
2006 will match 1995, also 11 years difference.
2007 will match 2001, a 6 year difference.
2008 will match 1980, a 28 year leap.
2009 and 2010, like 2005/06 will match the calendar of 11 years earlier
then again 6 and 28, 11, 11, 6, 28...
