Other mistake: Jack's parents were at a Halloween party when his mother went into labor. Later in the movie when he's asked by his teacher he says his birthday is September 12th.

Suggested correction: The movie doesn't specifically say this is a Halloween party. This may simply be a costume party which can and do happen multiple times a year.
As you stated, it doesn't say it's a Halloween party. In fact, there's signs in the room that say "Beaux-Arts Ball."

Continuity mistake: When Jack's mom takes him to school, she's barefoot in the front yard. The next shot at school, she's wearing shoes.

Suggested correction: She's not barefoot, you can see her shoes. They're the same ones she has on later.
