The Korean harvest holiday also known by the name Hangawi is Chuseok.
Hangawi is an older or alternative name for Chuseok, one of Korea’s most important traditional holidays. The word is associated with the middle of autumn, and the festival takes place around the full moon of the eighth month in the lunar calendar. Its timing places it near the period when autumn crops are being gathered.
Families commonly prepare songpyeon, visit ancestral graves, and hold memorial rites. Traditional clothing, folk games, music, and family reunions may also be part of the holiday. The full-moon setting helps explain why Chuseok is often linked with ideas of abundance, completion, and family unity.
Hangawi should not be mistaken for Seollal. Both are major Korean holidays based on the lunar calendar, but Seollal is the Lunar New Year, while Chuseok is the principal autumn family and harvest holiday.
