Short Girl Appreciation Day, also known as National Short Girl Appreciation Day, is observed worldwide every December 21, coinciding with the shortest day of the year in the Northern Hemisphere. The holiday originated in the 2010s, gaining traction on social media platforms like Twitter and Tumblr, where users expressed admiration for petite women and challenged societal beauty standards regarding height. Celebrations typically involve short girls treating themselves, hosting appreciation parties, or spending time with friends, while those of average height or taller are encouraged to acknowledge and support the short girls in their lives. The day also highlights the challenges faced by short women, such as difficulties in physical activities, reaching high shelves, and finding properly fitting clothing. Notable short female celebrities, including Marie Kondo, Dolly Parton, and Ariana Grande, serve as inspirations, demonstrating that height should not hinder success.
