Inspired by the United Nations, National Children's Day UK is an initiative dedicated to celebrating the rights and freedoms of children. This day serves as both a celebration and an opportunity to bring attention to projects benefiting children.

Emphasizing the significance of a wholesome childhood and the protection of children's rights, National Children's Day UK also sheds light on crucial topics such as fostering a healthier planet, revamping education, envisioning future cities, and understanding the impact of COVID on children's health and well-being. It provides a platform to showcase initiatives involving children, facilitate discussions, and host a variety of events, ranging from sports, drama, dance, art, literature, nature, to play.
