Today is already becoming “one of those days” 
A loosely written specification provided me with an ambiguity I did not account for: the client 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: http://stackoverflow.com/questions/1044921/a-good-business-calendar-library-in-java – how is everyone else solving this issue?
