The new calendar is a great idea, but probably won't get adopted.  The current system is complex but it can be handled by memorizing some small tables and learning to do mod 7 arithmetic in one's head.

Did you know that you can memorize the current month just by memorizing the day of the month that the first Sunday falls on?

Jan. 2012 is easy: 1

So for instance Jan. 18 will fall on a 4 or Wed. after subtracting multiples of 7.

By continuing with this method, one can mentally compute the day of the week for any date in history by memorizing some small tables.
