Friday the 13th

Been waiting for one to post this. From the Wikipedia article:

Over any given 400-year cycle the 13th day of the month occurs 4800 times. The distribution of 13th day of the month is as follows:

• Monday ( 685 or 14.27% ),


• Tuesday ( 685 or 14.27% ),


• Wednesday ( 687 or 14.31% ),


• Thursday ( 684 or 14.25% ),


• Friday ( 688 or 14.34% ),


• Saturday ( 684 or 14.25% ),


• Sunday ( 687 or 14.31% ).

This means the 13th day of the month is slightly more likely to occur on a Friday.
