Whilst looking around the Fairy Tail tag, I was looking again at a question
[here](https://anime.stackexchange.com/questions/7620/why-cant-natsu-and-
gajeel-go-through-freeds-runes) asked by Shinobu, I finally decided to pop the
question "How old is Natsu". I thought it would have been revealed further on
in the series, but from the looks of it they haven't although the ages of
Lucy, Erza and Gray have been revealed which is as follows

  1. Lucy- 17yrs
  2. Erza- 19yrs 
  3. Gray- 18yrs

Has an age ever been given in the mangas to how old Natsu is?

question
fairy-tail
Does Natsu have an known actual age?


I've never seen it mentioned, specifically, but we can get close to a minimum
age.

July 7, X777 is when the dragons disappeared. Since Natsu was trained by
Igneel, he must have been born before this date, presumably several years
before to allow time for training and such. If Natsu had been born the day
before, he would be about 14.

During the Fighting Festival arc, [the Battle of Fairy
Tail](http://fairytail.wikia.com/wiki/Fighting_Festival_arc#Battle_of_Fairy_Tail)
specifically, Natsu, Gajeel, and Makarov are trapped by Freed's enchantment,
suggesting that Natsu must be older than 80 at this point.

The [Edolas arc](http://fairytail.wikia.com/wiki/Edolas_arc) sees the return
of Gildarts after 3 year absence, suggesting the Battle of Fairy Tail was less
than 3 years prior to this. Since there is no minimum time that passed, there
is not much help to us here.

In the [X971 arc](http://fairytail.wikia.com/wiki/X791_arc) we know 7 years
have passed, so **Natsu must be at least 87** by this point.

Beyond that, I'm not sure how much time is passing between each event.

**Speculation**

I do have a theory that would make sense of why Natsu is so old when
physically he looks young:

> Natsu and the other Dragon Slayers are actually their respective dragons.
> For example, Natsu is actually Igneel.

  * July 7, x777 The Dragons disappeared
  * Natsu joined Fairy Tail in x777
  * Currently it is x791 in Fairy Tail world

From this it can be concluded that Natsu is **at least** 14 years old. **That
is the only thing we can know for sure**. But as to how old he really is,
there is no definite answer. The Battle of Fairy Tail suggest that he might be
older than 80 years old, but it was never mentioned explicitly that he is.

It is safe to assume that something inseparable from Natsu (his magic, a
sealed dragon, previous sealling like the 7 years thing) could have also kept
him from passing through the enchantment. Ergo, the 80 years seal cannot
nessesarily be used to develop a lower bound for his age. In addition, he
doesn't truely age when sealed away for 7 years. (Lucy was far too...
developed... to be 10 when she joined Fairy Tail).

For a lower bound of his body's age, we have to note that he remembers Ingeel.
Most first memories a child has are from 5 to 10 years of age (i'm the
latter). Their first clear memories are definitly around 10 years old.
Assuming Natsu must have been at least that old when Igneel disappeared, means
that in year X784 (when the series starts) Natsu would be roughly 17 years old
by this specific means of estimating his age. This puts him around the same
age as the others which makes sense. If he lived much longer than that,
(living time) he would remember having lived much longer than that and would
likely look like he had lived much longer than that.

I don't, however, believe his timeline is that simple. Zeref seem to remember
him which means he should be several hundred years old. The dragon slayers all
seem to have indeterminate ages that may be easily over 80 years old (as shown
by the previously mentioned enchantment).

So define living time as time he is conscious and sealed time as time he did
not age. Total age is living age+sealed age.

We do not know his age (living or sealled) as it is not yet revealled. **His
_living_ age is roughly 17-19 years old close to other main characters.** This
seems to be the measure used to define Lucy and the other's ages in the
question. His total age is at least 24 as he was sealled for at least 7 years.
His total age, however, as no upper bound and there is evidence that he (or
part of him) could be several hundred years old. The discrepency between
living and total age, however, all seems to be time sealled away by some yet
undefined means.

I would assume that Natsu is around the age of 17-18, because when he was
fighting Gray and when he joined Fairy Tail, he looked about the same age, as
I don't think that all the time travel with Eclipse would have affected it,
however, if they had the 7 year gap, so technically Lucy would be about 24,
but I think that we can say he is around the same age.

Also, it wouldn't make sense that he is 70 something, because, yes, the age of
dragons was around 400 years ago, but when the training is shown, he is the
only one there, not to mention the fact that Dragon slaying is a lost magic,
and is quite rare. Before the phantom lord incident, he didn't know that other
dragon slayers existed, and as a boy he didn't know how to read and write, so
he was quite clueless, surely in 70 years, he would have learn things!

In conclusion, if Guildarts left when he was 70/80 in a child form, and
returned 3 years later, he was in the state we see him now, considering that
Erza and the others grew at the same rate.

Natsu couldn't be 14 because he didn't meet Igneel when he was born. When
Igneel found Natsu alone in the woods, Natsu was able to walk properly, which
means that he had to be around 7. Igneel left when Natsu was around 12 and
spent around 5/6 years in Fairy Tail, not counting the years he skipped in the
Eclipse. Hence, Natsu is currently around 17 or 18.

Gildarts returned from "Century quest". That means he was gone for 100 years,
but he was with Natsu when he was little... so I think that in their time 100
years are maybe 3-5 years in real life. So... They are maybe several hundred
years old but they just don't age as quickly as in real life...

It would make sense - the age of dragons was 400 years ago so if 100 years =
~4 years then Natsu is around 16 + time before he met Igneel so around 17-20
years old in our world. Or like 500 years old in Fairy Tail universe!

Or... maybe they just count years in different way. Maybe "one year" is for
example 50 days long. So 365 days are 7 years not 1 or something... that's why
they put for example X780 year. That X is a number that changes not in 1000
years but faster.

Hope you liked my theory :)

All the current Dragon Slayers who were raised by Dragons have there parent
Dragon inside them. That's why it seems like they are more than 80 years old.

Natsu is older than Wendy, but younger than Erza, so his age would range from
14-17. I'm leaning more towards the older side.

Well it is hard determine the age as the dragon slayers have come from 400
years in the past.Technically Natsu is about 417-419 years old
