October 23rd is Mole Day.
No, it’s not about the underground rodent. Instead, it’s all about chemistry.
Mole Day is an unofficial holiday celebrated among chemists, chemistry students, and chemistry enthusiasts on October 23rd, between 6:02 a.m. and 6:02 p.m. 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 (mol) of substance. It is one of the seven base SI units.
Mole Day originated in an article in The Science Teacher in the early 1980s. Then-high school chemistry teacher Maurice Oehler founded the National Mole Day Foundation (NMDF) on May 15, 1991. Many high schools around the world celebrate Mole Day as a way to get their students interested in chemistry, with various activities often related to chemistry. In fact, the American Chemical Society sponsors National Chemistry Week, which occurs from the Sunday through Saturday during which October 23rd falls. Thus, Mole Day is an integral part of National Chemistry Week.
