To those who have successfully completed a Delta Elite Status Challenge:

If you get the challenge and earn your Silver or Gold Medallion status, when does it expire? Does it depend on if you finish the Challenge in the first 6 months of the year or the last 6 months of the year?

For example, if I completed the Challenge and gained Elite status in Feb 2006, would my status expire in the beginning of 2007 or 2008?
