How old is Harry wand?

Harry's wand is 11 years old at the start of the first book, *Harry Potter and the Sorcerer's Stone*.

Here's why:

* Harry's wand was purchased on his 11th birthday: His birthday is July 31st, and he buys the wand from Ollivander's on the same day.

* The series begins on Harry's 11th birthday: The first book begins with Harry's 11th birthday.

Therefore, the wand is the same age as Harry at the beginning of the series.
