On this day, at 11 a.m. sharp, James Sirius Potter, son of Harry Potter and Ginny Weasley, would have departed Platform Nine-and-Three-Quarters for on the Hogwarts Express.
J.K. Rowling was so kind as to remind us in a tweet this morning:
Cu-u-ute. But let's do a little math.
The Battle of Hogwarts ended in 1998 when Harry and crew were around 18 years old. For James Sirius to be 11 in 2015, he would have been born in 2004, when Harry was 24, and Ginny 23. That's pretty young, but so were James and Lily Potter when they had Harry in 1980 -- just 20 years old.
In any case, a few years from now, Harry's firstborn will be joined by his younger brother, Albus, along with Ron Weasley and Hermione Granger's daughter, Rose, and the son of Draco Malfoy and Astoria Greengrass, Scorpius Hyperion.
All of that just means that James, et al., will be sneaking the Maruader's Map into the castle for magical shenanigans before we know it.
Correction: A previous version of this post misstated the gender of Draco Malfoy's offspring. According to Rowling, Malfoy had a son, not a daughter.
