Celebrate Short Fiction Day, also known as National Short Story Day, is observed worldwide every December 21, coinciding with the shortest day of the year in the Northern Hemisphere. Established in 2013 by American author Nancy Christie, the day honors the short story in all its forms and recognizes the skill of short fiction writers. Participants are encouraged to engage in various activities such as writing new short stories, hosting workshops, and promoting short story collections through bookstores and libraries. The holiday aims to provide a perfect occasion to enjoy a well-crafted short story in one sitting, emphasizing that quality matters more than length in fiction. It invites readers, writers, and literary organizations to celebrate and share their love for short stories, often using the hashtags #CelebrateShortFictionDay and #NationalShortStoryDay on social media.
