At what point in the calendar year does it become clear that if you have once again newly "earned" diamond level again through 25 stays or 50 nights, would your status be granted all the way through until the following year?
For example, if you earned diamond status in April 2012, you would then have status until end of Feb. 2013, correct?
But if you earned diamond on July 15th, 2012, you would have status until Feb. 2014, correct?
