October 23 was Mole Day, celebrated by chemists, students, and buffs between 6:02 AM and 6:02 PM. However, it has nothing to do with the animal. In the American style of dating, the times would be 6:02 10/23, which is derived from Avogadro's number (approximately 6.23 x 10²³), the number of atoms or molecules in one mole of a substance.
