So I know that a lot of people want to know his age and all that, but we already have it... It's just that no one really took the time to calculate it.

In the episode "Visionary", Derek is 15. This episodes happens in 2002 because it’s the same year Jennifer Blake (aka Julia Baccari) is attacked by Kali. I know it’s the same year because in "The Overlooked", Jennifer says she survived because of the sacrifice of a virgin that happened a couple months ago (Derek mercy killing Paige).

So if you calculate this:

2011 (Year in Season 1-Season 2-Season 3A-3B) - 2002 (Year in ”Visionary”) = 9

15 (Derek’s age in 2002) + 9 = 24.

The Teen Wolf Universe is in 2012 now, either in January or February, so Derek might have already turned 25 because we dont know when his birthday is.

So there you go. We know how old he is.

24-25 years old.

Thank you. I know I'm not crazy and the only one who figured this out.
