I know that you all will be super-glad to hear that USAA has posted their 2013 Military Pay Posting Calendar. It is small here, if you click on the picture you will see it full-size.
From the number of people searching for USAA paydays, I know that there is a huge demand for this information. Thanks, USAA, for filling the need!
