~ Materia Usage ~

To create a distinction between the different kinds of entries in the timeline, I have marked them with several types of coloured Materia. The different Materia have the following meanings:

- Magic Materia -
Events with a clearly stated date, whether exact or approximate.

- Independent Materia -
Events that are known to take place, but do not have a clearly stated date or clear relation to dated events. I have tried to place these within the chronology as well as I can.

- Support Materia -
Events whose dates I have tried to estimate myself after known approximate dates. These are used for those events during the time of FFVII that have no specific dates assigned to them. I have tried to take conditions such as daylight, known periods of rest, time zones (to some extent) and similar in consideration.

- Summon Materia -
Events officially related to a game outside of the Compilation of FFVII (unlike Ehrgeiz, Kingdom Hearts or Dissidia).

- Command Materia -
Entries that are pure speculations from my part.

~ The Calendar of FFVII ~

Years in Final Fantasy VII follows a certain era system,
where one era appears to last for 2000 years.
They are written as follows: "[ ν ] - εγλ 0007"
(the year FFVII begins).
The Greek letter in square brackets indicates the current era
(in this case, "nu").
After 2000 years one era passes into another and the Greek letter
for the current era changes into a new one and the year resets to 0001.

There are twelve months in every year and seven days in every week.
The months and days go by their common English names.
However, the month of February has 30 days (at least this is the
case with the year [ ν ] - εγλ 0001), and there is no mention
of any month having 31 days (there is even an important festival that
takes place on October 30 instead of October 31).

Still, the years do not follow a perfectly regular 360 day cycle as the two
instances of dates with known weekdays, given in Crisis Core and Advent
Children Complete respectively, do not match each other in such a system.

The meaning of the three Greek letters εγλ
(epsilon, gamma and lambda), which appear together
regardless of the era, has not yet been revealed.

~ Further Theories ~

- εγλ -

Whereas the meaning of the letters εγλ is
unknown, a guess would be that it might be an abbreviation.
If so, the letters could stand for something like:

ε - epochi (era)
γ - Gaia (the name of the Planet)
λ - lego (tell)

Which could be made to mean something
such as:
"[era sign] - that which tells of this era of Gaia"

- [ Α ]-[ Ω ] -

The two known eras to be mentioned in the
Compilation of FFVII are called [ μ ] and [ ν ],
the twelth and thirteenth of the twenty-four
letters of the Greek alphabet. It could therefore
be assumed, since the letters indicating the two
known eras follow each other in alphabetical
order, that the current calendar system has
been in use for quite some time. In that case,
there would already have been eleven eras before the first known era of
FFVII ([ μ ]), during which humanity prospered after the disappearance
of the Cetra due to Jenova.
As each era appears to last for 2000 years, this would mean that 24007
years would have passed since the beginning of [ α ] (alfa) era at
the time of FFVII. This is why I decided to add, clearly marked with
either question marks and/or the speculative (Command) Materia,
the eras [ α ], [ λ ] and [ ϖ ] to the timeline.

Another interesting thing is that if the era calendar is indeed based on
the common twenty-four letters of the Greek alphabet, it will one day
end with [ ϖ ] (omega) era. If this would be meant to signify the
end of the world or the beginning of a whole new era, we can only guess.
Either way, this would occur about 23493 years after the last event of FFVII
(Nanaki and his children's visit to the overgrown ruins of Midgar).

Omega era... Such an ominous name. Maybe that is when Omega truly
should awaken and carry all life on the Planet to the sea of stars...
