Arbor Day was founded in 1872 by J. Sterling Morton in Nebraska City, Nebraska. By the 1920s, each state in the United States had passed public laws that stipulated a certain day to be Arbor Day or Arbor and Bird Day observance.

National Arbor Day is celebrated every year on the last Friday in April; it is a civic holiday in Nebraska. Other states have selected their own dates for Arbor Day.
This year marks the 150th anniversary of the tree planter’s holiday, and we’re excited to celebrate with you! In the last 50 years, the Arbor Day Foundation has planted and distributed nearly 500 million trees in more than 50 countries around the world to fight global issues facing humankind. And we’re just getting started.
