Notes

  1. ^ a b Roh and Lee served one day longer than other one-term presidents because they each served during two leap years while other one-term presidents served during only one leap year. This is also why their services of 4 years, 365 days did not equal 5 years
  2. ^ Suspended March 12, 2004 – May 14, 2004, Acting President: Goh Kun
  3. ^ Suspended December 9, 2016 – March 10, 2017, Acting President: Hwang Kyo-ahn
