Calendar system

The calendar system is a recurring feature in the Final Fantasy series, enabling chronological categorization of historical events. Every world has its own, different calendar system, resulting in several games sharing a calendar.
==Appearances==
===Final Fantasy VII series===
Dates are stylized as either "[ μ ] – εγλ" or "[ ν ] – εγλ". The changeover occurs from [ μ ] – εγλ 0000 to [ ν ] – εγλ 0001, presumably occurring in the wake of the official announcement of the Wutai War ending in February of [ ν ] – εγλ 0001. There are twelve months in a year and seven days in a week.
===Final Fantasy VIII===
The world calendar is similar to the real-world Gregorian calendar, with the same twelve months and year system. The characters' biographies list birthdays, but otherwise the calendar is not mentioned in the game itself.
===Final Fantasy IX===
Gaia's calendar is resembles the real-world Gregorian calendar with the same twelve months system. Year 0 is the date when Gaia's environment was recovering from the attempted fusion with Terra and the Shimmering Island began to shine, marking the beginning of Gaia's modern civilization. The story begins on January 15th, 1800, and ends on March 16th. Dates are rarely mentioned in the script, bar some inscriptions on statues. However, the Final Fantasy IX Ultimania has a full timeline.
===Final Fantasy XII===
The calendar used in Ivalice is the Old Valendia Calendar. It was started by the Galtean Alliance founded by Dynast King Raithwall of House Galtea. Its first year began with the creation of the Alliance.
It is unknown if the Project Memorandum found in the Urutan-Yensa bestiary follows this calendar, but if it does, this calendar would have 29 days in a month, but one year may mean more than 30 months.
===Final Fantasy XIII-2===
Following the fall of Cocoon, many of its residents have moved to Gran Pulse and adopted a new dating system of "AF" or "after the fall", with each subsequent year from the Catastrophe marked by the new letters. This dating system is used when utilizing the Time Gates of the Historia Crux. Some locations are labeled as "??? AF", indicating the time period is unknown. Sometimes, the efforts of Serah Farron, Noel Kreiss, and Mog to resolve a paradox may result in a new version of events within a particular location. Such altered worlds appear within the Historia Crux indicated with "X"s, i.e. "1X AF" or "4XX AF". The farthest known date normally visited is 700 AF, the Dying World. In the secret ending of Lightning's DLC episode, "Requiem of the Goddess", Lightning arrives in the Dying World five hundred years later at the end of time.
===Final Fantasy XIV===
In an attempt to unify the the world calendar, Lewphon from Sharlayan wrote "The Five Ages - An Eorzean Chronology" in the year 233 of the Sixth Astral Age. 
Each hour is affiliated with an element: Ice, Water, Wind, Lightning, Fire and Earth. Every four cycles of elemental hours have a "Sun", so a Sun has twenty-four elemental hours. A month is equivalent to a "Moon", which covers four cycles of eight suns and is therefore the sum of thirty-two suns. The eight is derived from the six elements and the two polarities, Astral and Umbral. 
The Year is made when the Moon orbits the two Astral and Umbral poles, fluctuating between the six elements. A Year can be said to be the length of twelve Moons. The first and second Moons of the Year are the first Astral and first Umbral, and together they share affinity with Ice. The second Astral Moon and the second Umbral Moon are the third and fourth Moons of the Year, successively with an affinity for the element Water. The fifth and sixth are the third Astral and third Umbral Moons, having affinity with the element Wind. The fourth pair of Astral and Umbral Moons has affinity with the Lightning element. Fifth Astral and Umbral Moons has affinity with the element Fire, and finally, the sixth Astral and sixth Umbral have affinity with the element of Earth.
The years consist of a cycle linked to the Twelve, so a set of twelve years is called an "epoch". The cycles of Astral Era and Umbral Era are another way of dictating eras. An Umbral Era is a dark period in which peace is broken and people struggle to recover, while an Astral Era is the period of abundance when peace returns until the arrival of the next Umbral Era.
===Final Fantasy XV===
The adoption of a unified calendar system across Eos is known as the start of the M.E. (modern era) time. Dates before this are denoted with A.E. (ancient era). The calendar used in Eos is the real-world Gregorian calendar, and has the same twelve months. The modern calendar system was established 755 years ago by the nations of Lucis, Niflheim, Accordo, and Tenebrae.
Dates are scarcely mentioned in the game, beyond the date of the newspaper that Ignis Scientia shows everyone in Galdin Quay.
===Final Fantasy Tactics===

===Final Fantasy Tactics Advance===
The calendar system advances one day for every step taken on the World Map. There are 5 months, and each month has 20 days in it. Each month is also representative of one of the races of Ivalice. If the number of units in the Clan decreases to 5 or less, a mission will become available in the Pub that allows one to recruit a new unit, whose race depends on the current month.
The months are, in order:
*Kingmoon - Month of the Humans.
*Madmoon - Month of the Bangaa.
*Sagemoon - Month of the nu mou.
*Huntmoon - Month of the Viera.
*Bardmoon - Month of the Moogles.
====Final Fantasy Tactics A2: Grimoire of the Rift====
A year in the Jylland calendar has 12 months, with each month made up of 20 days, so that one full year is the same as 240 days. With the region having four seasons; spring, summer, autumn and winter, each season spans three months.
The calendar is shown in this table:
Season	Months 	Months 	Months
Spring	Greenfire	Bloodfire 	Rosefire

The game was initially being developed for mobile phones, and the plan was to link real time with the game's progression by creating a calendar on the date the player starts the game, and the events and battles would be marked following along the real date and time. The team wanted to keep the concept of "playing along history" even after the platform was changed.
