Verizon Statement Date Problem

I wish to create custom date tokens representing the begin and end of the statement period. I will use it to rename the bill's file later in the rule.
My challenge is that the statement displays the statement period as follows:
Quick Bill Summary Dec 08 - Jan 07
Problem is: what is the year? Elsewhere, there are "bill dates" and "due dates" that state the year. How, if at all, can I programmatically use a third date to extract the year I can use for Begin and End dates?
I am not yet ready to concede using some estimation method to guess what year it is. Any ideas appreciated. John
