Talking About Your Age (The Korean Age System)

🌈 The Big Picture

🔢 Two Ages, One You: 한국 나이 vs. 만 나이

• Korean age (한국 나이 / 세는 나이) — Traditionally, everyone is born at "1" (not 0), and everyone gains a year together on New Year's Day (January 1st) — not on their individual birthday. So a baby born on December 31st turns "2" the very next day! This means your Korean age is usually 1–2 years higher than your international age.

• International age (만 나이) — The system used in most of the world: you're 0 at birth, and you gain a year on your actual birthday. As of June 2023, this became the official legal standard in Korea for things like contracts, medical records, and most paperwork.

• In casual conversation, many Koreans still think and talk in terms of 한국 나이, especially when figuring out social dynamics with someone close to their own age (e.g., for drinking culture, school years, or deciding whether to use 반말/casual speech). If there's ever doubt, people often just state their birth year (___년생) instead — that number never changes and avoids any confusion.

🛠️ Putting It Together

1. A: 몇 살이에요? B: 저는 28살이에요. 95년생이에요. [myeot sal-i-e-yo? / jeo-neun seu-mu-deol-deol-sal-i-e-yo. gu-o-nyeon-saeng-i-e-yo] — "A: How old are you? B: I'm 28. I was born in '95."
Adding your birth year after your age is extremely common — it lets the other person do the math in whichever system they prefer.

2. A: 저랑 동갑이네요! B: 진짜요? 그럼 우리 친구해요! [jeo-rang dong-gap-i-ne-yo! / jin-jja-yo? geu-reom u-ri chin-gu-hae-yo!] — "A: We're the same age! B: Really? Then let's be friends!"
Discovering you're 동갑 (the same age) often leads to switching to 반말 (casual speech) and a quick friendship — a very Korean social moment.

3. 손님 어른께: 실례지만 연세가 어떻게 되세요? [sil-rye-ji-man yeon-se-ga eo-tteo-ke dwoe-se-yo?] — "Excuse me, but may I ask your age?" (to an elderly person)
실례지만 ("excuse me, but...") softens the question, and 연세 (the honorific word for "age") shows respect — appropriate for grandparents, elderly strangers, etc.

🧭 Speaking Tip

⚠️ Pitfalls to Dodge

• ❌ Asking 몇 살이에요? to someone clearly older, a stranger in a formal setting, or your boss → ✅ 나이가 어떻게 되세요? (or avoid asking directly in very formal contexts).

• ❌ Assuming someone's "Korean age" and "international age" are the same number → ✅ They can differ by 1–2 years — if it matters, clarify or just share your birth year.

• ❌ Reacting with surprise or discomfort when someone asks your age → ✅ In Korea, this question is normal and often functions to establish how to speak to each other (formal vs. casual) — it's not considered rude the way it might feel elsewhere.

• ❌ Continuing to use casual speech (반말) with someone older just because you're close in age → ✅ Even a 1-2 year age gap can mean using 존댓말 (polite speech) unless they invite you to speak casually.
