Determining Service Computation Date


Q.  I am prior military servicemen who enlisted in the delayed entry program in December 1982 but went on active duty in the Marine Corps in March 1983.  Does this inactive ready reserve time count toward establishing my civilian service computation date, both before active and after active duty?   And also how does my active reserve time total into the SCD as well?

A. Active-duty service is the only military time that counts when establishing your service computation date. Reserve time, whether inactive or inactive ready reserve doesn’t count.
