QWhat is the first New Year?

AThis is the first New Year's Day after birth. When it was common to count people's age by years, age was counted by counting the day of birth as one year old, and each New Year’s Day was counted as an additional year. The First New Year has a special meaning of growing older for the first time. On the First New Year, "Hamayumi" bow and arrow ornaments are displayed for boys, and "Hagoita" battledore ornaments are displayed for girls to pray for the children’s safe growth.
