Online Accounting Masters Degree

How many weeks are classes for Masters Degree program at University of Phoenix (online)?

I got my associates degree through UOP by taking two classes at a time for 9 weeks. I am now working on my bachelors degree taking one class at a time for 5 weeks. I am just curious how it works if I decide to go for my masters in Accounting.
