I’m sure that you thought that all the excitement of the day was because it’s the anniversary of the Byzantine Empress Irene attending the final session of the second church council at Nicaea, Bithynia [now Iznik, a city in Anatolia (now part of Turkey)] on this date. The council formally revived the adoration of icons and reunited the Eastern church with that of Rome.
or the Feast day of St. John of Capistrano, patron saint of jurists,
and that all of the swallows are leaving Capistrano. But no, while you weren’t looking, it’s Mole Day once again. Mole Day is celebrated annually on October 23 from 6:02 AM until 6:02 PM – Mole Day commemorates Avogadro’s Number (6.02 x 10^23), which is a basic measuring unit in chemistry.
Mole Day was created as a way to foster interest in chemistry. Schools throughout the United States and around the world celebrate Mole Day with various activities related to chemistry and/or moles.
Don’t tell anybody that you celebrated this day.
