What Are the 24 Solar Terms?24절기란 무엇인가

Korea runs on a 2,000-year-old solar calendar — and you can still taste it in the food.

Ask when spring starts in Korea and you may get an oddly precise answer: February 4th. That's Ipchun, one of the 24 jeolgi — solar terms that divide the year into segments of about 15 days, each named for what nature is doing: 'insects awaken,' 'grain rain,' 'frost descends.' Here's the twist: although Korea traditionally used a lunar calendar for holidays like Seollal and Chuseok, the jeolgi are purely solar, based on the sun's position along its yearly path. Farmers needed the sun, not the moon, to know when to plant and harvest, so the two calendars ran side by side. The system was formalized in Han-dynasty China over 2,000 years ago and spread to Korea, Japan, and Vietnam; UNESCO inscribed the 24 solar terms on its Intangible Cultural Heritage list in 2016. In Korea the jeolgi shaped not just farming but food, proverbs, and daily rhythm — and they quietly persist. Korean phone calendars still mark each term. On Dongji, the winter solstice, families eat red-bean porridge to chase off bad spirits; around Ipchun, hand-brushed blessings appear on doorways. Weather forecasters cite jeolgi names on the news. Learn a few of them, and Korean small talk about the seasons suddenly makes a lot more sense.

한국에서 봄이 언제 시작되느냐고 물으면 이상하리만치 정확한 답이 돌아온다. 2월 4일, 입춘이다. 입춘은 1년을 약 15일 간격으로 나눈 24절기의 하나로, 각 절기의 이름은 그 무렵 자연의 모습을 담고 있다. '벌레가 깨어난다(경칩)', '곡식을 적시는 비(곡우)', '서리가 내린다(상강)' 같은 식이다. 흥미로운 점은, 설날·추석 같은 명절은 음력으로 쇠면서도 절기는 순전히 태양의 위치로 정해진다는 것이다. 농사에는 달이 아니라 해가 기준이었기에, 두 달력이 나란히 쓰였다. 이 체계는 2천여 년 전 중국 한나라 때 완성돼 한국·일본·베트남으로 퍼졌고, 2016년 유네스코 인류무형문화유산에 등재됐다. 한국에서 절기는 농사뿐 아니라 음식과 속담, 생활 리듬까지 빚어냈고, 지금도 조용히 살아 있다. 스마트폰 달력에는 여전히 절기가 표시되고, 동지에는 나쁜 기운을 쫓는 팥죽을 먹으며, 입춘 무렵이면 대문에 붓글씨 축원이 나붙는다. 일기예보도 절기 이름을 인용한다. 절기 몇 개만 알아두면, 계절을 화제로 한 한국인의 일상 대화가 훨씬 잘 들리기 시작한다.

If you go가신다면

Getting there.가는 법. National Folk Museum: Seoul Metro Line 3 to Anguk or Gyeongbokgung Station, short walk through the palace grounds. Korean Folk Village: direct shuttle or city bus from Gangnam Station / Suwon Station (about 1 hour from Seoul).

Tips.팁. The National Folk Museum's permanent exhibition walks through a full Korean year of seasonal customs — a perfect primer before traveling the countryside. Time a visit to a jeolgi date for special programs: folk villages and hanok villages often hold Dongji porridge-sharing or Ipchun calligraphy events. Check each venue's website around solstices and the start of each season.

Best time.가기 좋은 때. Any season — but visiting on a jeolgi date (Ipchun in early February, Dongji in late December) adds live customs to the experience.
