  • 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 31.

  • 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 31.
  • Your birthday has already occurred this calendar year, so you gain exactly one year in the traditional system.
  • You will gain a traditional Korean year in 112 days on January 1st.
  • Your international birthday is in 338 days.
