Clerihew Day is celebrated on July 10 to honor the four-line poetic form created by Edmund Clerihew Bentley. This day invites individuals to engage in crafting witty verses, encouraging creativity and humor in poetry. Observed primarily in the United States, participants are encouraged to share their clerihews on social media platforms like Instagram and TikTok, often using hashtags to connect with others. While it may not be a major retail holiday, interest in poetry often leads to promotions on writing supplies and literature from various online and independent bookstores. Activities may include writing contests and sharing personalized clerihews about friends or famous figures, fostering a lighthearted spirit among participants.
