World Poetry Day is on March 21, 2023. It was declared by UNESCO (United Nations Educational, Scientific and Cultural Organization) in 1999. The purpose of the day is to promote the reading, writing, publishing and teaching of poetry throughout the world and, as the UNESCO session declaring the day says, to "give fresh recognition and impetus to national, regional and international poetry movements".
World Poetry Day was generally celebrated in October, sometimes on the 5th, but in the latter part of the 20th Century the world community celebrated it on 15 October, the birthday of Virgil, the Roman epic poet and poet laureate under Augustus. The tradition to keep an October date for national or international poetry day celebrations still holds in many countries. Alternately, a different October or even November date is celebrated.
Poetry is a form of literary art in which language is used for its aesthetic and evocative qualities in addition to, or in lieu of, its apparent meaning. Poetry may be written independently, as discrete poems, or may occur in conjunction with other arts, as in poetic drama, hymns, lyrics, or prose poetry. It is published in dedicated magazines, individual collections and wider anthologies. (With material from: Wikipedia)
