The Harvest Moon Festival is a celebration by farmers across Daire? and Nubia? on the day of the full moon nearest the autumnal equinox? as a way to give thanks for the summer's bounty and to mourn the coming of winter.

As part of the celebrations, those who can manage it are expected to donate food to the poor during the two weeks either side of the Harvest Moon to help get them through the winter. Those who can but don't are ostracised by their local community for the coming winter so they'll be forced to manage alone; this is a grave punishment in smaller communities where neighbourly charity is vital for survival.

The main celebration is a feast that takes place on the day of the Harvest Moon, featuring foods from the crops just harvested. There is much music and merriment, and any locals with musical ability are asked to provide entertainment for the evening so others can dance.
