Use the Entry Name and the Token Editor

Name Token = %(Entry Name#<^(.*)-\d+>#)

Month Token = %(Entry Name#<.*(\d\d)\d\d\d\d\d\d$>#)

Day Token = %(Entry Name#<.*(\d\d)\d\d\d\d$>#)

Year Token = %(Entry Name#<.*(\d\d\d\d)$>#)

To explain, let's start at the end.  "$" means the end of the input. "\d" means any digit.  The "(" & ")" go around the information in the pattern that you want to return. The ".*" means anything 0 or more times.  And finally, "^" means the beginning of the input.

Then to find the name, we go from the start of the input and grab anything until we find a dash followed by 1 or more digits.  To find the month, we get the left most 2 digits of an 8 digit string starting from the end of the input.  To find the day, we get the left most 2 digits of a 6 digit string starting from the end of the input.  And to get the year, we get the 4 digits at the end of the input.
