What is Arbor Day?

Arbor Day, which is Latin for "Tree Day," is an environmental holiday where citizens and groups are encouraged to plant trees and care for the already existing trees. Arbor Day was founded by J. Sterling Morton on April 10th, 1872 in Nebraska City, Nebraska, United States where over an estimated one million trees were planted on that single day. 

The United States celebrates Arbor Day on the last Friday in the month of April while other countries celebrate on various dates through the year.
