The Korean name for the first full moon of the lunar year is Jeongwol Daeboreum.
Jeongwol Daeboreum is a separate Korean festival observed on the fifteenth day of the first lunar month. Its name means “Great Full Moon” of the first month, and its customs include eating special foods, cracking nuts, and participating in regional games and fire-related celebrations.
The festival is sometimes confused with Chuseok because both are major seasonal holidays connected with the full moon and the traditional lunar calendar. They occur in different lunar months: Daeboreum in the first month and Chuseok in the eighth.
Chuseok’s moon-related symbolism belongs to the autumn harvest season, while Jeongwol Daeboreum marks the first major full moon of the new lunar year. Knowing the month prevents the two holidays from being treated as interchangeable.
