[rjsvlawv] Days of the week and month

What is the day of the week distribution for February 29?

I've heard the 13th is most likely to fall on a Friday, ironically.  Conversely, what are the most likely days of the month for a Friday?  Presumably 6, 13, 20, and 27 equally likely.

This should be easy, 400 year Gregorian cycle.
