By the end of the 19th century, Memorial Day ceremonies were being held on May 30 throughout the nation. State legislatures passed proclamations designating the day, and the Army and Navy adopted regulations for proper observance at their facilities.
The first official Arbor Day Celebration was held in Cincinnati, Ohio in 1882, and two new elements were entered into observance. First, the day was declared a school festival, second the practice of planting a memorial tree was inaugurated. These new developments were largely responsible for the acceptance of Arbor Day over the rest of the United States. Arbor Day became an official day of observance in Mississippi in 1926. Later, the second Friday in February was firmly adopted as the day on which the state would annually observe Arbor Day.
