Did you know? Today (January 6th) marks the day Harry Potter began to learn the Patronus Charm

Some people celebrate holidays, birthdays - even the day you get your paycheck - but the nerdiest Potterheads among us have something else to think about today, January 6th, 2013. Did you know that on this day in 1994 Harry Potter bagan to take lessons with Professor Lupin so that he could learn the high-level Patronus Charm, a magical defense against Dementors?

That's right, it's true - and don't tell us it didn't happen, because you're a Muggle if you don't believe! Because we're mega-fans here over at MuggleNet we've created a unique calendar which fans can use to keep track of a plethora of important Potter-related dates, including birthdays of the actors and book characters, notable events from the series, dates of Harry Potter conventions, and even standard Muggle holidays. It's all in this magical 2013 calendar and more!

Did you know January 6th also marks the day Dumbledore first showed Harry that "sluggish memory" in 1997? Hmm. We bet you didn't. But if you order the MuggleNet calendar now you'll be able to stump your friends next time like we just stumped you - and have all the more to celebrate!

While we're on the topic of dementors, patronuses and Professor Lupin, we'd like to remind you MuggleNet Alohomora! just kicked off its rereading of Harry Potter and the Prisoner of Azkaban, and we'll be releasing a podcast in which we analyze the first two chapters of the book next Saturday.
