10 U.S.C. § 14006 — Determination of years in grade

This section applies to chapters 1403 through 1411 of title 10. For all of those chapters, an officer's "years of service in a grade^*" are counted starting from that officer's date of rank^* in that grade. The date of rank itself is determined the way section 741(d) of title 10 sets out. So whenever another provision in these chapters asks how long an officer^* has served in a grade, the answer is calculated from this officially set date of rank, not from some other date like when the officer was actually notified or began performing the duties.
