Mole Day from Prairie du Chien, Wisconsin, founded the National Mole Day Foundation (NMDF) on May 15, 1991. Many high schools around the United States, South Africa, Australia, and Canada celebrate Mole Day as a way to get their students interested in chemistry, with various activities often related to chemistry or moles. The American Chemical Society sponsors National Chemistry Week, which occurs from the Sunday through Saturday during which October 23 falls. This makes Mole Day an integral part of National Chemistry Week. Mole Day Mole Day is an unofficial holiday celebrated among chemists, chemistry students and chemistry enthusiasts on October 23,
