* Neville Longbottom: His birthday is mentioned as being a few days before Harry's, which is July 31st. This implies Neville's birthday could be in late July or early August.
* Luna Lovegood: While her exact birthday is not mentioned, she is described as being a "November baby" in the "Harry Potter: The Character Vault" book. However, this source isn't considered official canon.
It's worth noting that most Harry Potter characters have their birthdays in the summer months. This might be due to J.K. Rowling's personal preference or a storytelling device to highlight the importance of summer in the wizarding world (e.g., the Hogwarts school year).
