National Arbor Day — 24 April

Broadleaf. Evergreen. Conifer. How well do you really know your trees? Now you have a goal for National Arbor Day.

America’s first Arbor Day took place toward the start of the 1870s — right around the time Congress established Yellowstone National Park. Celebrate nothing less than humanity’s endearment toward nature on April 24, just four days after Earth Day. 

Note: National Arbor Day always falls on the last Friday in April, but many states observe Arbor Day on different dates throughout the year based on their best tree planting times. That varies widely. For example:

Florida — Third Friday in January

Alaska — Third Monday in May

Hawaii — First Friday in November
