Korea's biggest holiday falls on the fifteenth day of the eighth lunar month, and the country essentially stops moving for three days while everybody travels home.

Families visit ancestral graves, cut the grass and share songpyeon, half-moon rice cakes shaped deliberately like a moon that is not yet full — the tradition being that a growing moon is the more hopeful shape. It is the same full moon as China's Mid-Autumn and Vietnam's children's festival, kept three different ways.
