December is the highest month, February second. There is actually an explanation for both of those.
Dec has to do with a sale practice followed by DVD for many years and to a more varied extent even followed now. A new purchaser in any given year would usually get a use year that started three to five months before the sale month (it was a sales aid -- you immediately get points that can be used or banked and not far away were the next use year's points). Dec was being used as the main use year start month for sales made March through May mainly because both Nov and Jan were not use years.
Feb is mainly a result of opening dates and sales before opening. BLT, whose highest use year month by far is Feb, is the best example. BLT opened in Aug 2009. That was actually earlier than its initially described likely opening time of Fall 2009. It went on sale to existing members in Sep 2008 and new purchasers in Oct 2008. However, the earliest starting use year it sold was Feb 2009, If it had tried to sell an earlier start month such as Oct 2008, and something happened to prevent the resort from opening before Oct 2009, all purchasers with an Oct 2008 use year would have had a right to rescind the sale. Moreover, for a number of months after Feb 2009 that is the start month most new purchasers got, e.g., even after Feb 2009, it was the chosen start month for about four months of sales so that new purchasers got the earliest possible start date before the sales date. So essentially BLT had about nine consecutive months of sales in which Feb was the main use year being sold.
