When is National Mole Day? October 23!
Mole Day is an unofficial holiday celebrated among chemists in North America on October 23, between 6:02 AM and 6:02 PM, making the date 6:02 10/23 in the American style of writing dates. The time and date are derived from the Avogadro constant, which is approximately 6.02×1023, defining the number of particles (atoms or molecules) in a mole, one of the seven base SI units.
Origin of this Holiday?
"Mole Day originated in an article in The Science Teacher in the early 1980s. 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."
What is this holiday about?
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. Since 2007 Mole Day has been celebrated in Smålandsstenar in Sweden.
Alternate observances
• Some schools celebrate Mole Day on June 2 (6/02 in MM-DD format) and occasionally February 6 (6/02 in DD-MM format), rather than October 23 (10/23), presumably from 10:23 AM to 10:23 PM.
• Some schools celebrate "Mole Week" around October 23.
• The American Chemical Society sponsors National Chemistry Week, 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.

How is this holiday celebrated?
This holiday is celebrated by having a "Chemist get together"! Yep today can be party time so get out the latest chemistry project or chemist game and have some fun. Swap ideas and celebrate! That's right, gather everyone together for a few drinks and snacks and delight in the fact that chemistry is your T-H-I-N-G!

What is Chemistry?
"Chemistry (from Egyptian kēme (chem), meaning "earth") is the science concerned with the composition, behavior, structure, and properties of matter, as well as the changes it undergoes during chemical reactions. It is a physical science for studies of various atoms, molecules, crystals and other aggregates of matter whether in isolation or combination, which incorporates the concepts of energy and entropy in relation to the spontaneity of chemical processes. Modern chemistry evolved out of alchemy following the chemical revolution (1773)."
