How do I calculate the seasonality in a time series forcast that has 12 month time period?

I know how to find the moving average...I am having problems figuring out the Centered Moving Average as well as the ratio to CMA...and once I have that figured out, how do I calculate the seasonality numbers? If anyone can help I would greatly appreciate it!
