How old is John in the New 52 run?

Additionally, what issue range would that age equate to in the Hellblazer comic run?

I am interested too.

I think Constantine on Hellblazer from issue one itself was 30 so much older than the current run.

By guess, I'd put him somewhere along the mid to late twenties. Zatanna is around that age in the new 52, and the two have been romantically involved. So it sort of makes sense.

What about his age on the show?

Probably in his early to mid 30's.

Matt Ryan is in his thirties, so I'm guessing John in the show is around that age.

Would you say 34? About the same age he starts in the comics?

I would think that he would be mid twenties since most of the characters in the New 52 were closer to mid thirties before the relaunch. Batman is in his mid twenties again and so is Green Arrow. So it just kinda makes sense.

Constantine #22 lists his Earth 2 counterpart as being born in 1985, so if John is the same age he would be about 29.

Most Earth 2 counterparts are older.

@dondave: He can't be that much older though, and they looked almost exactly the same age.
