National Promposal Day is celebrated on March 11 and is recognized primarily in the United States. This day honors the creative and elaborate ways in which individuals ask their partners to prom, known as promposals. The concept of the promposal is believed to have originated in 2001, although its exact history is unclear. National Promposal Day was officially established by Men’s Wearhouse, who identify as "Certified Promposal Enthusiasts." Typical activities for this day include watching promposal compilation videos that showcase the creativity and effort of high school students. Participants may also reminisce by finding their old prom attire, such as dresses or tuxedos. The day serves as a celebration of romance and creativity among high schoolers.
