WHAT YEAR IS IT, AFTER ALL?
"Mid-18,230 of the Common Era, plus or minus 25 years, referenced to J2000 standard."
This year-length standard was pushed for being a convenience for the Chelok majority of the workforce and commercial fleet, being equal to their standard Ecumenical Year, used on the Pancalestia's capital, Dheghom.
Kulman Calendar - year 13,139 from the world's creation
The Kulman Calendar was a popular standard of timekeeping used by the ancient Kulman peoples, a coalition of nomadic tribes spanning the largest continent of Dheghom. With its year 1 set around 5099 CE or 9576 BdF, during the early years of colonization of the planet by the Ancestors.
It continues to be insularly used today among few countries across Dheghom out of tradition, in which case, the Year of Prime Foundation would be counted as 9,526 KE.
Yellow Calendar - year 20,952 of the Yellow Emperor
The Yellow Calendar used on Khemedra carries a much older tradition of timekeeping than the others reported here. Claiming its year 1 in 2698 BCE, dating the ascension of a legendary emperor known as the Yellow Emperor, which is said to have ruled a culturally significant region of the Cradle of Humanity (Nam Arde), known as China.
This timekeeping tradition along with many Khemedrani customs, history, and culture were deemed heretical by the Nastiche Church, at the same time it held a certain cultural and historical gravitas due its connection claims to the Ancestors and the Cradle, and research on it was deemed highly questionable.
Today the Yellow Calendar is one of those traditions that has mostly been phased out of use by the intensive integration efforts of Khemedrani global civilization to the larger Pancalestia. For reference, the Year of Prime Foundation would be expressed as the year 17,348 of the Yellow Calendar.
Ecumenical Calendar - year 10,501
The Ecumenical Calendar, like the Yellow Calendar is also based on a legendary emperor figure, but one of a much less favorable reputation (by modern standards) than the Yellow Emperor. In 7,780 CE, the Chord Rebellion on Dheghom put Ader Kal'rev II at the top of a global coup, declaring Ader II 'God-Emperor of Mankind', while also establishing a more 'modern' unified calendar with its year 1 at the first year of his reign.
Even though the God-Emperor title and its xenophobic interstellar campaigns had ended by around 620 of the Ecumenical Era, by the establishment of the Veroh Emperor ruling through the Veroh Samir Naminai – the Ecumenical Calendar continues to mark just how culturally connected humanity across the Pancalestia has been ever since.
Core Hoku colonies such as Muhori and Sideshoku utilize the standard Sidessian Military Time calendar, which is the same utilized by the Expanse Navy – whereas Dominion diaspora Hoku timekeeping drink more from the socio-historical construct of the "Stellar Era" calendar, with its year 1 in 13,726 CE, some 255 years (~353.77 Hoku-years) after the founding of the Commonwealth of Sidessia and the founding year of the Hoku Expanse.
That would make the Year of Prime Foundation the year 1,635 of the Sidessian Calendar, and year 1,282 of the Stellar Era.
