Hm, taking this with the followup that Jim posted, it's not unreasonable to consider that perhaps Twilight is around 24 years old (hey, I like to imagine Twilight as the same age as me - being that I see a lot of myself in her, and vice-versa), which, if you would assume the egg hatching test to take place after Magic Kindergarten (so Twilight would be around 6 or 7 years old) means that Spike would be about 17-18 in pony years but 11-12 in dragon years (which certainly seems reasonable).

Headcanon accepted.
