Evan:
This is a case where year doesn't apply. The field is for businesses that are seasonal and the recipient of the data wants to know the month and day the business opens and closes. Here in Kalamazoo, MI, the Root Beer stand ( an old A&W Root Beer location) opens March 1st every year and closes when the weather starts to get cold. I was hoping there was a control already written, but that's why WE GET PAID the big bucks.
