#MoleDay is celebrated among chemists, chemistry students and chemistry enthusiasts on October 23, between 6:02 AM and 6:02 PM. The time and date are derived from Avogadro's number, which is approximately 6.02×1023, defining the number of particles (atoms or molecules) in one mole of substance, one of the seven base SI units.
