Remember that Avogadro's number is 6.02 x 1023​.  This means that Mole Day is from 6:02 AM to 6:02 PM on October 23rd (this is the 23rd day of the 10th month).  This is a festive day amongst chemists around the world.  Let's make this year's Mole Day the best ever!  (And, by the way... "Talk Like A Pirate Day" is on September 19th!).
