James, the majority of the posts I see here from you are always rude remarks. This is meant to be a helpful community verses always trying to fight against individuals, so I would recommend dropping the bashes against others and just replying with a simple "sorry, couldn't find it with a search" and leave it as that.
Anyway, to help answer your question, it varies, but the Marriott Concierge usually posts something in Late February to Early March each year. I did a "quick search" that took about 5 seconds and yielded these results for you.
Marriott Rewards Hotel Category Changes - Early March 2014
Marriott Rewards Hotel Category Changes - Mid February 2013
Marriott Rewards Hotel Category Changes - Late February 2012
So based upon the past three years, it was anywhere from mid February to early March.
Happy New Years
