October 23: Mole Day

From 6:02 a.m. to 6:02 pm on October 23 (10/23), chemistry fans everywhere celebrate Mole Day and Avogadro’s number: 6.02 x 10^23. In case you wanted to see it, that’s


There are many types of moles in the world – moles you find digging in your backyard, moles you whack on the head in an arcade, moles you find on your skin, moles who infiltrate organizations and pass on their secret information . . . the list goes on. Nevertheless, October 23 is dedicated to the unit of measurement. The concept at first seems a bit complicated, but it’s more than worth the effort to understand since it simplifies so many problems in chemistry.

I’m not a great science person generally, so I had to get some help for celebration ideas (at least, more advanced ideas than “discuss the mole with your chemistry class”). Here’s a list of Mole Day projects and (even better) a page of Mole Day jokes both from the National Mole Day Foundation, Inc. Knock yourself out!

“If you call out for insight
and cry aloud for understanding,
and if you look for it as for silver
and search for it as for hidden treasure,
then you will understand the fear of the Lord
and find the knowledge of God.”

Proverbs 2:3-5
