Military Discharge Date Calculator FAQ
What service term is this based on?
This uses the current service terms set by Article 18 and Article 42(1)(1) of Korea's Military Service Act: 18 months for Army/Marine Corps, 20 months for Navy, 21 months for Air Force, and 21 months for social service agents.
Could my actual discharge date differ from this result?
Yes. This calculator simply adds the standard service term to your enlistment date. Actual discharge may be delayed by unauthorized absence, disciplinary education, or sentence enforcement, or come early in some cases (such as social service agent release). Check with your unit or the Military Manpower Administration for your exact date.
Does this cover active-duty reserve or industrial technical personnel?
This calculator only covers Army/Marine Corps, Navy, Air Force, and social service agents. Other service types, such as active-duty reserve or industrial technical personnel, have different service terms — please check the Military Manpower Administration's guidance separately.
This calculator adds the standard service term under Article 18 and Article 42(1)(1) of the Military Service Act to your enlistment date, for reference only — it may differ from your actual discharge date. For an exact date, check with your unit or the Military Manpower Administration (1588-9090).
