Meaning and Origin

Mangjong means “sowing the seeds (種) of grains with awns (芒).” It is the solar term when barley is harvested and rice is planted, making it the busiest time of the year for farming households. The Korean saying “At Mangjong, you urinate on your own instep” captures just how hectic the season was.

Customs and Foods

People tasted the new grain through “bori-geuseureum,” roasted newly harvested barley, and used the weather on Mangjong to divine the year’s farming prospects.

Saju and Solar Terms

The calendar of Myeongli astrology moves by solar terms. Mangjong is one of the 12 solar term nodes (節), and from this day, the month pillar (月柱) in Saju changes to the O (午) month. This is why solar terms, not lunar calendar dates, are the standard when determining the stem-branch of a person’s birth month.

Wisdom for This Time

When everything piles up at once, priorities become your best tool. Start by planting the one thing that must be planted today.

Solar terms are a seasonal calendar that divides the sun’s path into 24 parts. This is a traditional explanation based on the climate of the Korean Peninsula, and the actual date can vary by about a day each year.
