I am going through the IDES process and am in the process between the finishing of my ratings from the VA and that paperwork going back to the PEB. When I receive the PDIR...I plan to retire at the end of a month, like a 28th or 29th and be on the retired rolls the 29th or 30th respectively. When does retirement pay begin? When will DFAS begin paying retirement pay? Is retirement pay effective the immediate 1st day of the month (as in a few days later)? or is there a waiting period like there is with the VA?
