About this tool
This calculator estimates the discharge date of South Korean conscripts from the enlistment date.
Pick a branch and it applies the standard service length: 18 months for the Army and Marine Corps, 20 months for the Navy, and 21 months for the Air Force and social service personnel.
The enlistment day counts as day one, so the last day of service is normally the day before the same calendar date months later. If that month has no matching date, such as the 31st, the last day of the month is used.
You also get days served, days left, a progress bar and a D-day countdown. It is handy for fans following the enlistment and discharge schedules of Korean celebrities, and for partners and families waiting at home.
These are the current lengths; if the enlistment was before or during the 2018–2020 service-reduction period, the real length can differ. This is an estimate only.
Leave, discipline, early-discharge rules and policy changes can shift the real date, so confirm with the unit or the Military Manpower Administration (mma.go.kr). Your input is saved only in this browser.
