Thirty-seven years ago on this day, September 19, Hermione Jean Granger came into this world.
Well, technically she came into the world of "Harry Potter." Jury's still out on whether that world is real or not.
Point is, it's Hermione's 37th birthday today, and Hermione is a witch worth celebrating.
For her part, JK Rowling celebrated with a tweet: a picture of Emma Watson and Noma Dumezweni, who is playing Hermione in "Harry and the Cursed Child."
In the interest of continuing the Hermione love, I thought we could take a look back on all the times Harry Potter probably would have died had he not had a friend like Hermione.
1. That time she saved him from Devil's Snare.
Luckily, Hermione paid attention in Herbology, or else 11-year-old Harry probably would have never relaxed and instead struggled death with the Devil's Snare in "Harry Potter and the Sorcerer's Stone."
And it's also a good thing she remembered the rhyme that reveals the plant's weakness — sunlight — or else Ron would definitely be dead.
2. That time she solved Snape's logic puzzle.
If you haven't reread the first book in a while, you might have forgotten about the potion's puzzle posed by Snape to guard the Sorcerer's Stone.
Harry and Ron basically let Hermione handle this one — which she does, masterfully, and saves them all from drinking poison.
3. That times she figured out the monster in "Chamber of Secrets" was a Basilisk.
Even when she was paralyzed, Hermione was still finding all the answers for Harry.
Tom Riddle was dangerously close to opening the Chamber of Secrets, but luckily Hermione figured out not only was the monster petrifying students a Basilisk, but it was using the plumbing to travel.
Had Harry not found that piece of paper in her hands, he never would have stopped Tom Riddle in time.
4. That time she didn't let Harry meet him past self and open up a space-time vortex.
Remember in "Prisoner of Azkaban" when Harry wanted to confront his past self and warn him about Peter Petrigrew but Hermione was like "nah"? Yeah, good call, Hermione.
5. That time she taught Harry the Summoning Charm.
Hermione spent a good portion of her fourth year at Hogwarts teaching Harry to use "Accio," the summoning charm.
This spell has come in handy for Harry not only for winning the first task of the Triwizard Tournament but also for escaping Lord Voldemort in the graveyard by summoning the portkey.
6. That time she convinced Harry to check on Sirius before rushing off to the Department of Mysteries.
In "Order of the Pheonix," Hermione persuaded Harry to check on Sirius using Floo Powder before going off to save him from Voldemort.
Even though, unfortunately, Sirius wasn't home, Snape would have never been able to warn the Order and send back-up if she hadn't done that.
7. That time she got Harry and Ron the heck out of that Weasley wedding.
Harry and Ron were totally unprepared when the Death Eaters crashed Bill and Fleur's wedding — luckily, Hermione had them covered. She even packed them clothes.
8. That time she saved Harry from Nagini.
Hermione was suspicious going back to Godric's Hollow was a recipe for a trap, and she was right. Luckily, she was there to save Harry when Nagini emerged from Bathilda Bagshot's rotting corpse.
Happy birthday, Hermione, and thanks for making sure The Boy Who Lived kept on living.
Hopefully Harry got you one helluva a present this year.
