Mole Day is an unofficial holiday celebrated among chemists, chemistry students and chemistry enthusiasts on October 23, between 6:02 AM and 6:02 PM,[1][2][3][4] making the date 6:02 10/23 in the American style of writing dates. The time and date are derived from Avogadro's number, which is approximately 6.02×1023, defining the number of particles (atoms or molecules) in one mole of substance, one of the seven base SI units.

Overview[edit]

Mole Day originated in an article in The Science Teacher in the early 1980s.[5] Inspired by this article, Maurice Oehler, now a retired high school chemistry teacher from Prairie du Chien, Wisconsin, founded the National Mole Day Foundation (NMDF) on May 15, 1991.[5]

Many high schools around the United States, South Africa, Australia and in 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,[2] which occurs from the Sunday through Saturday during October in which the 23rd falls. This makes Mole Day an integral part of National Chemistry Week.
