Friday the 13th (Posted on 2004-08-13)

Which day of the week (Sunday, Monday, etc.) is the probability largest to fall on the 13th of a random month, in a random year?

Or is this probability the same for each day of the week?

Sorry, Charlie, there was another careless bug in my program that was not correctly calculating leap years. After correcting that, I get Friday as the most likely day, as you also do.
