Moon-Viewing Day is an annual event in Harvest Moon: Back To Nature. It is held on the 13th day of Fall, between 6:00 pm and 11:50 pm, at the Summit of Mother's Hill.
On the night of Moon-Viewing Day, the moon is at its most beautiful. When the player enters the Summit of Mother's Hill, the girl with the highest affection will be waiting at the overlook. The game will skip the remainder of the current day without saving progress.
