When is National Mole Day?

Monday October 23rd

We'll ban any images of a burrowing creature's celebrations right away; National Mole Day honors a unique number in chemistry. On October 23rd, chemists and chemistry students mark the occasion each year.

National Mole Day | October 23

#nationalmoleday

The celebrations, more specifically, take place between 6:02 AM and 6:02 p.m. on June 2, 2002 AM. :02 AM. The time and date are written 6:02 10/23 in the United States. Avogadro's time and date are calculated from Avogadro's number. The number of Avagadro's number is 6.021023.23. Hence, one of the seven base SI units, determining the number of particles (atoms or molecules) in a single mole of a substance is therefore one of the seven base SI units.
