Mole Day

October 23, 2021 @ 06:02 - 18:02

|Recurring Event (See all)

An event every year that begins at 06:02 on day 23 of October, repeating indefinitely

When:
October 23,
06:02 – 18:02 GMT
Where:
Everywhere
First occurrence:
1980-something
Mole Day was first mentioned in an article in
‘The Science Teacher’ in 1980-something.

Inspired by this article, high school chemistry teacher
Maurice Oehler, from Prairie du Chien, Wisconsin,
founded the National Mole Day Foundation (NMDF)
on May 15, 1991 to promote that chemistry is fun!
🐾🧮
The date is inspired by the Avogadro number for
calculating the number of particles in one mole of
any substance.

A mole is a measuring unit used in chemistry to
measure very small units of substance.

Because numbers and chemistry can be boring when
only used for calculations, making fun of those numbers
makes them easier to remember and an extra reason
to make class more fun.

🧮
The time was picked as a number play on
Avogadro’s Number (6.02 x 1023).
And that is why this day is not a whole day
but from 06:02 to 18:02.
