Exact dates and times for all 24 Korean solar terms in 2026: Ipchun, Chunbun, Haji, Dongji and more. Traditional Korean seasonal markers based on the sun's ecliptic longitude.
Entry times for the 24 solar terms are based on data from the Korea Astronomy and Space Science Institute (KASI) and are for reference. Astronomical calculations may vary by ±1–30 minutes.

The 24 Solar Terms (24節氣) are a Korean traditional calendar system dividing the year into 24 segments based on the sun's ecliptic longitude. Ipchun (Spring begins) falls on February 4 in 2026, Haji (Summer Solstice) on June 21, Chubun (Autumn Equinox) on September 23, and Dongji (Winter Solstice) on December 22. Each term spans about 15 days and has deep cultural significance in traditional Korean farming, cuisine, and customs.
Since they are based on the sun's position (ecliptic longitude), the Gregorian dates are nearly the same each year but shift by ±1 day. For example, Ipchun falls on February 3 or 4. They're based on the solar calendar, not lunar.
The exact instant when the sun's ecliptic longitude reaches a specific angle (e.g., 0° for Chunbun, 90° for Haji). Each solar term officially begins at this precise moment, not at sunrise. KASI publishes these times each year.
Each solar term has associated traditional Korean dishes: red bean porridge on Dongji, Osinchae salad on Ipchun, and barley rice on Haji. These dishes reflect centuries of wisdom about seasonal nutrition and farming in Korea.
Dongji 2026 is at 05:50 on Dec 22 — the longest night. Haji is at 17:24 on Jun 21 — the longest day. Ipchun (Feb 4) and Dongji (Dec 22) are the most culturally significant terms in Korea.
