Service Complete 🎉
The discharge date calculator takes your enlistment date and computes your discharge date and current service progress based on the service term for the Army, Navy, Air Force, Marine Corps, or alternative (social) service.
Service terms by branch
The standard terms are 18 months for Army/Marine Corps, 20 months for Navy, 21 months for Air Force, and 21 months for alternative social service. Adding the service term to the enlistment date gives the discharge date, and the elapsed proportion up to today is shown as service progress.
Frequently Asked Questions
Am I discharged on the discharge date itself?
The discharge date is typically the day your service term ends, and discharge is generally processed as of that date, though details can vary by unit and branch.
Does leave or basic training count toward the service term?
Regular and reward leave are included in the service term, since the calculation runs from enlistment date through discharge date.
Why is the term different for alternative social service vs. active duty?
The type of service and the legal basis under the Military Service Act differ, so alternative social service runs longer than active duty (Army/Marine Corps).
