On this day in 1991, Harry first met Prof. Snape in his first potions class.

Harry learned of bezoars and Snape’s hatred for him.

This marks a big occasion for Harry as it begins his rivalry with a man more than 20 years his senior who behaves like a whiny child.

On this day in 1995, Harry has his first detention with Dolores Umbrage…only five days into the school year.  What a troublemaker! Umbrage, of course, was all set to revolutionize teaching at Hogwart’s but found her way thwarted and blocked at every turn by that muggle-lover, Albus Dumbledore.
