& Continuous Learning

Today is already becoming "one of those days" ;)

A loosely written specification provided me with an ambiguity I did not account for:  the partner wanted expiration dates and ordering dates to be based upon business days, whereas the specification said "days" only.  So, I found myself scrambling to figure out the best way to perform date functions against a business day concept.  I found some solid information here. - how is everyone else solving this issue?
