National Twin Day is a day dedicated to celebrating twins and the unique bond they share. It is observed annually on August 3rd in the United States and other countries around the world. The day was first established in 2014 by Twin Sisters Day Foundation, a nonprofit organization that supports and empowers twins.
National Twin Day provides an opportunity for twins to connect with each other, share their experiences, and celebrate their unique bond. It is also a day to raise awareness about the challenges that twins face, such as discrimination and bullying.
