Which date does the Seniority Dates process incorporate and update based on rules?

• A. Anniversary Year Ending (AYE)
• B. Basic Active Service Date (BASD)
• C. Pay Entry Base Date (PEBD)
• D. PESTEMPO events

Answer: (A)

Seniority dates are kept in sync with an annual cycle, and the update rules use the Anniversary Year Ending as the anchor for recalculating a member’s seniority. When service actions occur (such as reenlistment, transfer, or changes in status), the system applies these rules relative to the most recent anniversary-year end, ensuring the seniority reflects where you are in that yearly cycle. This approach maintains a consistent ordering for pay, promotions, and retirement timing across personnel records.

The Basic Active Service Date marks when active service began and is a fixed starting point, not the annual anchor used for ongoing seniority updates. The Pay Entry Base Date serves pay calculations and entitlements rather than driving seniority recalculations, and PESTEMPO events relate to deployment tempo rather than a date used to update seniority.
