World Poetry Day is a United Nations holiday celebrated on March 21 every year. It was officially founded by UNESCO in 1999. Its purpose is to promote the reading, writing, publishing, and teaching of poetry throughout the world. One of the main objectives of the day is to support linguistic diversity through poetic expression and to offer endangered languages the opportunity to be heard within their communities. April is also Academy of American Poets National Poetry Month, which is celebrated in both the U.S. and Canada.
