Oh, dude, Ginny Weasley is around 15 or 16 years old in "Harry Potter and the Half-Blood Prince." Like, she's in her mid-teens, dealing with teenage drama, Quidditch matches, and crushing on a certain bespectacled wizard. So, yeah, she's not quite an adult yet in that book.
Ginny entered Hogwarts at age 11 in Harry Potter and the Chamber of Secrets, the second book. Harry Potter and the Half-Blood Prince is the sixth book, so Ginny would be 15 at the start of that book. The author has said that Ginny's birthday is 11 August, so Ginny would be 15 throughout the book.
At the time the film version was made, Bonnie Wright, the actress who plays Ginny, was apparently 18 years old.
