Is the program year April - March?

I have never had a CET card before. I plan to (ab)use the daily tier credit multipliers to get 7* and see what I can get out of them (hoping to double dip on offers when I am in town for MGM events, and perhaps score free rooms for friends in the process). I figure that it makes the most sense to start at the beginning of the program year (so I can get as close to 2 years worth as possible, even if I decide to stop playing there).

I'd be interested in hearing the rumors about program changes! I just hope they don't get rid of the 10k bonus tier credits for earning 5k in a day
