The Mole Day is an unofficial party held by chemists and chemistry students on October 23 in honor of mole, a unit of measurement in chemistry.
The mole measures chemical entities as atoms or molecules and is formally defined as the amount of any substance that contains as many entities as there are atoms in 12 grams of carbon-12.
Associated with the number of Avogadro, a dimensionless measurement unit in Chemistry, the mole approximates 6.02 × 10^23. The name is named after the Italian scientist Amedeo Avogadro.
6:02 a.m. at 6:02 p.m.
Mole Day is celebrated annually between 6:02 a.m. and 6:02 p.m (18:02) on October 23 because when it is written in month-date format, the date and time 6.02, 10^23 include the digits in the Avogadro number.
The National Day Day Foundation, founded in 1991, celebrates the day every year with a theme. Some of the recent topics include Molar Eclipse in 2012, Mole of the Caribbean in 2010 and Molar Express in 2009.
How to celebrate?
Get your geek for this day. Wear a polka dot shirt and when someone asks you about it, explain the concept of a mole.
Have a mole themed party and serve “mole” and wear mole costumes (the animal).
Did you know …
… that a group of moles is called labor?
