National Grammar Day is observed in the United States every March 4. Established in 2008 by author Martha Brockenbrough, who also founded the Society for the Promotion of Good Grammar (SPOGG), the day aims to help students engage with grammar in a lively and positive manner. It encourages the celebration of language rather than fear of it. Teachers, editors, journalists, and writers participate by creating blog posts, lessons, and lectures focused on grammar. Celebratory activities include taking grammar quizzes, attending grammar lessons, reading books on grammar, or teaching others about grammar. The holiday emphasizes that grammar is important in any language, allowing for participation even from those outside the United States or who speak languages other than English.
