Tiny tools for everyone curious about Korea.

Five tiny questions about Korea, answered in three seconds.

How old am I in Korea? What's my name in Hangul? Do I call them oppa or hyung? Rule-based, sourced, and made to be shared β€” every answer shows the official rule behind it.

Why these are accurate

  • Romanization follows the official Revised Romanization and its sound-change rules (μ’…λ‘œ β†’ Jongno, not Jongro) β€” verified against every example in the regulation.
  • Korean age explains the 2023 law: legal age is your international age, and we tell you where β€œyear age” still applies.
  • Name spellings come from National Institute of Korean Language usage records when they exist β€” and are clearly labelled when they are estimates.
