32 se
  • Born (Korean age 1)
  • Korean adulthood (19 se)
  • Middle age (40 se)
  • Hwangap (60th birthday)
  • Classical old age (70 se)

Your traditional Korean age is 32; your international age is 30.

  • In the traditional Korean counting system you are 32 se. Under the international system (now the legal standard in South Korea since June 28, 2023) you are 30.
  • You gain two years in the traditional system rather than one because your birthday has not yet occurred this calendar year.
  • You will gain a traditional Korean year in 146 days on January 1st.
  • Your international birthday is in 7 days.

Next stepFor official documents, contracts and legal purposes in South Korea, the international (man-nai) age has been mandatory since June 28, 2023.
