September 15, the National Day of Double Cheeseburgers, Doodling, and DOTS! When it comes to International Dot Day, we join in celebrating the creativity, courage, and curiosity of young minds. It’s a day to recognize the power of imagination and to encourage our next generation to explore their own creativity. Dot Day was originally inspired by Peter H. Reynolds’ book, The Dot, and it has been bringing joy to children across the globe ever since.
