Children's Day began on the second Sunday of June in 1857 by Reverend Dr. Charles Leonard, pastor of the Universalist Church of the Redeemer in Chelsea, Massachusetts: Leonard held a special service dedicated to, and for the children. Leonard named the day Rose Day, though it was later named Flower Sunday, and then named Children's Day.
