Poem in Your Pocket Day is celebrated annually on April 29 in the United States to encourage self-expression through poetry. The holiday originated in New York City when the Office of the Mayor, along with the Departments of Cultural Affairs and Education, declared it a day for poetry appreciation. Participants are encouraged to write their own poetry, perform their work, or create art inspired by poetry, fostering a connection to this living art form. The initiative aims to remind individuals of the importance of poetry in personal expression and cultural heritage.
