What is Mole Day?
Mole Day is celebrated annually on October 23 from 6:02 a.m. to 6:02 p.m., Mole Day honors Avogadro's Number 6.02 x 10^23, which is a basic measuring unit in chemistry. Mole Day was created as a way to foster interest in chemistry. Mole Day is widely celebrated, in educational institutions, and is quite a tradition in High Schools in the United States and Canada.
How did it start?
Mole Day traces its origins to an article that appeared in The Science Teacher magazine in the early 1980s about a high school chemistry teacher's reasons for celebrating the day. The idea for Mole Day took root. The National Mole Day Foundation was formed on May 15, 1991. The American Chemical Society plans National Chemistry Week so that Mole Day falls within the week. Today Mole Day is celebrated around the world.
