Boreumdal is the Korean name for the full moon viewed during Chuseok celebrations.
The word combines boreum, meaning a full moon or full-moon day, with dal, meaning moon. Chuseok occurs at the full moon of the eighth lunar month, so moon imagery is central to the festival’s seasonal symbolism.
People may admire the moon, make wishes, or connect it with family hopes and agricultural abundance. Moon viewing is a broader East Asian tradition, but Korean Chuseok gives it a distinctive place within harvest and ancestral customs.
Boreumdal should not be confused with dalmaji, a Korean term for the act or custom of greeting and viewing the moon. The moon itself and the activity of watching it therefore have different Korean terms.
