October 23 Mole Day

Today day is October 23 Mole Day observed every year by chemists and chemistry students in honor of the little burrowing creature.

This celebration takes place between 6:02 AM and 6:02 PM, making the date 6:02 10/23 in the American style of writing dates. The time and date are derived from Avogadro’s number, which is approximately 6.02×10^23, defining the number of particles (atoms or molecules) in one mole of substance, one of the seven base SI units.
