A day-care center is a place where children can be supervised and cared for while their parents are at work or just need to run errands. It is also known as a child-care center, nursery, preschool, or kindergarten. A nursery school provides early education and help in developing social and cognitive skills for children aged two to four. A preschool is similar to a nursery but also involves structured learning to prepare children for kindergarten. Kindergarten is typically for children aged five to six and focuses on academic preparation and socialization. A child-care center is a broader term encompassing all these different types of facilities that cater to children's care and well-being.
