What Date of Rank means
Date of Rank is the official date associated with a member's grade. It is used for seniority and time-in-grade calculations.
Why A1C DOR matters for BTZ
The Senior Airman fully qualified calculation uses time in grade as an Airman First Class. An incorrect A1C DOR can shift the estimated normal promotion date and BTZ date.
Use the verified DOR in the USAF BTZ Calculator.
Do not substitute a ceremony date
The date you pinned on rank, graduated, arrived at a base, or received paperwork may not be the official DOR. Use the date shown in official records.
