How it's calculated

The discharge date is the day before the service period (in months) has passed since enlistment. For example, an Army soldier who enlisted on March 2, 2026 is discharged on September 1, 2027. Actual dates can change with leave use or early discharge programs.

Promotions (Army)

Typically, promotion to private first class is on the 1st of the 3rd month, corporal the 9th month, and sergeant the 15th month. It varies with unit circumstances and promotion reviews.
