Mole Day
is an
unofficial holiday
celebrated among chemists,
chemistry
students, and chemistry enthusiasts on October 23 between 6:02 a.m. and 6:02 p.m.,
[1]
[2]
[3]
[4]
making the date 6:02 10/23 in either
MDY or YMD date formats
. The time and date are derived from the
Avogadro constant
, which is approximately
6.02
×
10
23
, defining the number of particles (atoms or molecules) in one
mole
(mol) of
substance
, one of the seven base
SI
units.
Overview
[
edit
]
Mole Day originated from a celebration by educator Margaret Christoph.
[5]
She wrote an article about her experiences in
The Science Teacher
in the 1980s.
[6]
Inspired by this article, Maurice Oehler, a
high school
chemistry teacher from
Prairie du Chien, Wisconsin
, founded the National Mole Day Foundation (NMDF) on May 15, 1991.
[6]
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.
[6]
The
American Chemical Society
sponsors
National Chemistry Week
,
[1]
which occurs from the Sunday through Saturday during which October 23 falls. This makes Mole Day an integral part of National Chemistry Week.
