Korean has a real fondness for naming exactly where you are in life. Some of these words are casual and get thrown around in everyday conversation. Others come straight out of the Analects (the writings of Confucius and his disciples) and only show up in speeches, obituaries, or a grandparent's toast at a birthday dinner. Today we're going through both sets — the everyday phase words and the Confucian age markers — so you can recognize them wherever they show up.

The everyday phase words

These are the ones you'll actually hear in conversation, dramas, and song lyrics. They describe a stretch of life rather than a specific age.

• 유년기 — early childhood. Formal-sounding, shows up in writing more than speech.
• 사춘기 — adolescence, specifically the turbulent, moody, hormonal stretch of it. If a parent says their kid is "사춘기가 왔다" (사춘기 has arrived), they’re probs having a rough time at home ㅎㅎㅎ
• 청춘 — literally "blue spring." This is youth as an idea, not just an age range
• 전성기 — someone's peak, the stretch when they were performing at their absolute best. Works for athletes, actors, companies, even countries. "그의 전성기는 20대 후반이었다" — his peak was his late twenties.
• 한창때 — a looser, more conversational cousin of 전성기. Less "career peak," more "the prime of your life," and it's often used a little wistfully, looking back. 한창 on its own means "in full swing," so 한창때 is when everything was in full swing.
• 중년 — middle age, plain and neutral.
• 황혼기 — literally "the twilight period." 황혼 by itself just means sunset.
• 말년 — the final years, whether of a life, a career, or even a military service term (말년 병장 is a running joke about soldiers coasting through their last weeks of service).

The Confucian age markers

You won't reach for these in everyday conversation, but they're good to have on your radar so you recognize them when they show up. These come from a passage in the Analects where Confucius describes himself at each decade of life. They're old, they're formal, and Korean adopted them wholesale as fixed nicknames for specific ages. They tend to surface in speeches, formal writing, and birthday celebrations for the milestone ages.

• 약관 — 20 years old, specifically for men. Literally "the weak crowning," referring to the coming-of-age ceremony where a young man first put on the adult's cap despite not yet being physically mature.
• 방년 — a woman's twenties, especially around 20, meaning "fragrant years." You'll see this in older writing describing a young woman as being in the bloom of youth.
• 이립 — 30 years old, "standing firm." The age by which Confucius said he had established his principles.
• 불혹 — 40 years old, "no longer confused." The age of no longer being swayed by doubt.
• 지천명, often shortened to 지명 — 50 years old, "knowing the mandate of heaven."
• 이순 — 60 years old, "ears attuned." The age at which one can hear anything without being disturbed by it.
• 고희 — 70 years old, "rare since ancient times," from a Tang dynasty poem noting how few people lived that long. Also called 종심, "following the heart," meaning you can act on your impulses without overstepping.

These pair naturally with birthday parties for the milestone years. A 60th birthday (환갑) traditionally gets a bigger celebration than most others, partly because of the 60-year cycle in the Korean zodiac calendar. We chat more about this in our post about the new year.
