4 Calendars of Exflora

The World of Exflora has 4 main Calendars to record the passage of time. They all represent the same periods of time but have different numeric and symbol values for the years themself.
The Document called "4 Calendars of Exflora" is actually a collection of documents making up a unifying translation or equation that allows comparisons and synchronizations between the 4 major world calendars.
The four calendars do not all begin on the same date each year and the Star Calendar counts 20 Standard Calendar Years as one Star year and the Visigoth Calendar has slightly different lengths for each year in a wave pattern that makes every year's length longer or shorter, but after a ten-year series of Visigoth years, the total number of days matches the equivalent of 10 years of the Standard Calendar.
The 4 Main Calendars are:

1. The Standard Calendar: Used mostly on The Continent of Karnak , The Continent of Mydridlands and The Continent of Rusdaysia
2. The Ambover Calendar: Used mostly on The Continent of Romalia
3. The Visigoth Calendar: Used mostly on The Continent of Stabatia
4. The Star Calendar: Used only on The Continent of Zerebim

The Standard Calendar

Current Year	15082
First Year (assumed to be but lost in time) But the calendar can be theorised to be older, as before year 1, we calculate the years in reverse order as BSC (Before Star Calendar)	Year 1
Days in each year	457

The Ambover Calendar
The Ambover Calendar is calculated by Eons Each year has an Eon Prefix and the year designates the year within that Eon.
The Eons have various lengths and the total years in each Eon is listed Below

Eon - /./ D	114 years (ongoing)
Eon -/./ )-I	15,000 years
Eon -/./ (+	489 years
Eon -/./ )-(	1,070 years
Eon -/./ L=	700 years
Eon -/./ oI	Length Unknown
Eon -/./ L-	Length Unknown
Eon -/./ @	Length Unknown
Eon - /./ =	Length Unknown

The Modern interpretation of the Eon Year Symbols is listed below:
_/.^/ D , _/.^/ )-I , _/.^{/ (}₊ , _/.^/ )-( , _/.^/ L= , _/.^{/ o}_I , _/.^/ L- , _/.^/ @ , _/.^/ =

First Year (lost in time)	Unknown
Days in each year	457

The Visigoth Calendar
The Visigoth Calendar has used a new central letter every 1000 years to notate the passing of the Millennium. There is a conference in the 900th year of the current Millennium to decide what the next letter will be for the next Millennium.
Visigoth Calendar has slightly different lengths for each year with some years having 457 days and others having 460 and others having 454. Occasionally they will have 452 days and 462 days. The lengths of the years follow a traditional 10-year rotation of long and short years that averages out the length of each year to 457 days.

The Star Calendar
The Star Calendar is the strangest of all the calenders as each year lasts for a full 20 rotations of the run therefore each year actually lasts for 20 years. So you may have statements like the 17th year of 72**62. The origin of this behaviour is lost in time and no actual record has been kept as to why it is like this.
