Well, basically I came to the same conclusions: the month of Tragos is January, if you consider the Greek Zodiac (Tragos = month of the Goat = Capricorn). We know from the Aerial log that on Tragos 13th, the "Claudia Units Capture" operation starts (ep. 22). On that very day the Trial of Agoon takes place too. From the picture of the calendar you posted it is obvious to assume that Dio's birthday is on Tragos/January 15th.

So, on that day Dio turns 17... it is January 15th, 665 G.D.

Here are my speculations:

Now, to connect LE1 and LE2 with a possible timeline, we know that:
- LE2 takes place almost 2 years after LE1;
- it is 6 months since Dio has joined the Sky Pirates (LE2, ep.4 - that's what Fam tells Millia);
- about 2 years earlier the Silvius appeared in Western Lierre (LE2 ep. 4 - Fam (or Gisey?) to Millia during dinner)
According to the booklets for LE2, Dio is now 18 and Tatiana is 19.

Moreover, it can be assumed from the anime that Fam turns 16 on October 28th: if you look closely to the calendar that Gisey checks (ep. 09) you can read Dictionary Day and Sweetest day, and these point to October.

So... trying to set a timeline...

Jan. 665 - End of the War on Prester preparation of the Exile;
Feb. 665 - The first immigrants from Anatoray-Disith return to the blue planet with the Exile;
Spring 665 - first contact with the Earth guild (hourglass manga)
Summer 665 - The Silvius is ready thanks to Guild technology and Anatoray-Disith military. The Silvius is first seen in W. Lierre;
Jan. 666 - Dio turns 18
Feb. 666 - the second year on earth begins;
Apr. 666 - Dio joins the sky pirates of Kartoffel
Sept/Oct. 666 - Peace talks between Turan and Ades - Fall of Iglasia - it is 6 months since Dio joined the pirates, it is almost 2 years since the Silvius appeared (actually 1 year and 2-3 months...

Oct. 666 Fam captured/gone skyfishing for Tatiana
Oct. 28th, 666 - Fam's birthday
Nov. 666 - War on Glacies
Dec. 666 - Operation "Grand Exile"
Spring 667 - The 2nd Grand Race

As for the age of some characters:

G.D.664: Claus 15 - Alvis 11 - Dio 16 - Tatiana 17 - Fam 14
G.D.665: Claus 16 - Alvis 12 - Dio 17 - Tatiana 18 - Fam 15
G.D.666: Claus 17 - Alvis 13 - Dio 18 - Tatiana 19 - Fam 16

Well... it can be improved XD

Nice to know I wasn't the only one who caught the calendar in episode 9 and Fam's birthday. XD That's part of how I was going about looking up things (and because I was curious about the texts on the calendar to see if it said anything interesting and LO AND BEHOLD)

So Spring coming at the end of Fam means Dio at least had another birthday between Grand Exile and the Grand Race, since he actually has a more or less set birthday unlike ... pretty much everyone else aside from Fam.

Well, while reading page 133 of "Last Exile Chronicles" I discovered that we actually have set dates for Claus' and Lavie's birthday.

Claus was born on Krios 28th, 644 G.D.
Lavie was born on Karkinos 14th, 644 G.D.

Apparently the names of the months in LE are those of the signs of the greek zodiac:

Tragos (Capricorn, however this is an exception because in Greek the name of the month should have been Aegokeros)
Hydrochoos (Aquarius)
Ichthyes (Pisces)
Krios (Aries)
Tauros (Taurus)
Didymoi (Gemini)
Karkinos (Cancer)
Leon (Leo)
Parthenos (Virgo)
Zygos (Libra)
Scorpios (Scorpio)
Toxotes (Sagittarius)

Now, we have two possibilities:

either these names replace those we use in our calendar, i.e.
Tragos = January
Hydrochoos = February
Ichthyes = March
etc...

or these months correspond to the astrological signs i.e.
Tragos = 22 Dec. - 20 Jan.
Hydrochoos = 21. Jan. - 19 Feb.
Ichthyes ) 20 Feb. - 20 Mar.
etc...

... but then Tragos would have 30 days, and this does not match with the calendar shown in the anime.

Anyway...

I hope I didn't make mistakes either with the translation or with my English ^^

TK

HUH.

That stuff is on the wiki timeline but not with the months. I guess Chronicle basically took some of the Aerial Log timeline (since the wiki timeline was translated from AL) only added some extra small things as well as dates. (like the 661 stuff was just CLAUS AND LAVIE LERN 2 FLY AND SELL HOUSE)

You can at least make out 31 days on the October calendar in ep9, so it might be more corresponding with the months (and Dictionary Day is on the 16th still).

I also love how that gives us specific dates for things like the Grand Stream cross attempt. '-'

THIS IS AWESOME though I wonder why Tragos is the odd one out. EITHER WAY SWEET you kick ass for checking that out (since I wouldn't have, I'm so JP'd out on doing novel stuff I'm like SCREW EVERYTHING THAT DOESN'T HAVE DIO'S NAME IN IT) These are fun little things I love bringing up in RP as well so ahhh so happy.

Concerning Tragos...

...maybe the writers were into Gundam Wing, because there is a Tragos mobile suit (OZ-07MS, see http://en.wikipedia.org/wiki/List_of_Mobile_Suit_Gundam_Wing_mobile_weapons and the corresponding Japanese topic http://ja.wikipedia.org/wiki/アフターコロニーの機動兵器) among the ones named after the Zodiac constellations. That mobile suit is not named after an actual constellation, although it is considered to represent Capricorn.

Moreover the name "Tragos" is waaaay easier than "Aigokeros" ^^"

So far the confirmed names are Tragos (from the anime), Ichthyes, Krios, Tauros, Karkinos, Parthenos, Zygos and Scorpios (from page 133 of "Chronicles"). I have yet to check if other names are used in Chronicles. For the moment Ydrochoos, Didymoi, Leon and Toxotes are the best guess based on the Greek Zodiac.

However, if I am not mistaken the booklet of the Italian edition of LE1 contained the names of the 12 months in its glossary section. I'll check that too.

BTW: correct spelling:

Τράγος = Tragos = Goat (Αιγόκερως = Aigokeros = Capricorn)
Υδροχόος = Ydrochoos = Aquarius
Ιχθύες = Ichthyes = Pisces
Κριός = Krios = Aries
Ταύρος = Tauros = Taurus
Δίδυμοι = Didymoi = Gemini
Καρκίνος = Karkinos = Cancer
Λέων = Leon = Leo
Παρθένος = Partheos = Virgo
Ζυγός = Zygos = Libra
Σκορπιός = Skorpios = Scorpio

♥ Wow, this is all so interesting, particularly the Alex and Sophia bits for me... So Sophia was about 10 when she entered the academy? I wonder who was captain of the Silvana before Alex and what happened to them.

....Kinda makes me want to go back and completely re-write Wild Birds, but it would confuse people, and I'm way too lazy to do it.

How old is Sophia?
That's a mystery...

Alex turns 28 in G.D.665. Sophia should be 19 (or 20) years old. (I say "19 or 20" because it is not said whether her stated age (i.e. 19) refers to G.D.664 or 665).

So it seems she entered the military academy when she was 9 or 10.

But her actual age is not so clear! Well, according to the Aerial Log (page 113) she is the "Silvana vice-captain, 19 years old". But that's just a quick note in the "setting data" section.
According to the "Spheres Character Filegraphy" she is "19(?)". Yes, with a question mark in brackets!
According to Chronicles (page 57) "she says she is 19 years old". It is the only character whose age is expressed in this way: 自称１９歳. Alex is just 28歳.

So maybe she is older than she says...

There's something in the "Staff Table Talk" of the Aerial Log about her age, maybe I'll do that later...



Back to the months. Everithing is confirmed, but... with a twist!

From the "large Encyclopedia" section of the Aerial Log (page 66).

山羊月　(トラゴス)
アナトレーの暦法での月の一つ。
他の月名は、年の初めからトラゴス、ヒュドロコオス、イクテュエス、クリーオス、タウロス、ディデュモイ、カルキノス、レオーン、パルテノス、ジュゴン、スコルピオス、トクソテースとなる。
アナトレーの季節ではトラゴスが真夏となる。

Month of the Goat (Tragos)
One of the months in the calendar system of Anatoray. Starting from the beginning of the year, the names of the months are Tragos, Ydrochoos, Ichthyes, Krios, Tauros, Didymoi, Karkinos, Leon, Parthenos, Zygos, Scorpios and Toxotes.
As for the seasons in Anatoray, Tragos serves as midsummer.
