This NAVADMIN formally announces the promotion boards and sets the zones. My post a few days ago, though, is points you to the lineal list, which is the easiest way to figure out where you are in relation to the zones.
The promotion boards of note are:
- 6 FEB 2018 – Staff Corps Captain
- 27 MAR 2018 – Staff Corps Commander
- 15 MAY 2018 – Staff Corps Lieutenant Commander
It also contains the instructions for communicating with the promotion boards, and all communication is now due 10 days before the boards start.
