Over the past three seasons of Once Upon a Time, we’ve seen Henry Mills (Jared Gilmore) grow up quite a bit. He started out being the only person in Storybrooke who believed in all the fairytale mumbo jumbo, and now he’s wandering around with no memory of it at all. Now that Jared has been on our TV screens for the past few years, we’re curious as to how old the child actor actually is.

Jared was born on May 30, 2000, which makes him 13 years old. A whopping 65 percent of voters correctly guessed that he is just in his first year of being a teenager while the rest of the votes, 19 percent and 16 percent, were split between 15 years old and 11 years old, respectively.

It’s hard to believe that Jared is about to turn 14 later this year. We’re so glad we’ve gotten a chance to see him grow up on OUAT. Hopefully his character will stick around for a long time.

Once Upon a Time airs Sunday nights at 8 p.m. ET on ABC.
