Why Is Korean Age So Complicated?

👥 Why Do Koreans Ask Your Age First?

Age plays a big role in Korean culture. Influenced by Confucian traditions, respect is often shown based on age. That’s why people ask your age right away — it helps them choose the proper titles and speech level (formal or informal).

🔢 What Are Korean Age Types?

Koreans have traditionally used 3 different age systems: Korean age (세는 나이), international age (만 나이), and year age (연 나이). It can get confusing for foreigners!

• Korean Age (세는 나이): Starts at 1 at birth. Everyone gains a year on January 1st.
• International Age (만 나이): Starts at 0 at birth, gains a year on your birthday. Since June 28, 2023, this is the legal standard in Korea.
• Year Age (연 나이): Calculated by subtracting birth year from current year. Used in military service and youth protection laws.

🗓️ What Is "Fast Born" (빠른 년생)?

Before 2009, children born between January and February could start school a year early. These early-born students were called "fast-born" and were grouped with students born the previous year. Although the system no longer exists, the term is still used in conversations.

🐉 What Does "Zodiac Age Mate" (띠동갑) Mean?

Korea follows a 12-year zodiac cycle. People who share the same zodiac sign (every 12 years) are called "띠동갑". However, this doesn’t imply age equality — respect should still be shown if there’s a big age gap!

📅 Age Unification Law

Since June 28, 2023, Korea has officially adopted international age (만 나이) for all legal, administrative purposes. This change helps simplify documents, contracts, and everyday life — especially for foreigners.
