Federal Calendar and Time System
Federal Calendar
At the dawn of interstellar travel, historians of Human Interplanetary Alliance were met with two peculiar facts: Populations of newly discovered human inhabited worlds were genetically related to people from core worlds and each other with a minor drift of only few dozen generations. Also, each of these civilizations had no historical accounts prior to the past millennium and some of them shared myths of “coming from the sky”.
Based on these findings, the Exodus Theory was established. It explained all these human-inhabited worlds with a major Exodus Event from one single planet of origins. After prolonged debates across the Human Interplanetary Alliance, a commonly accepted Day of Exodus was agreed upon and the Humanity’s Common Calendar was established.
The Day of Exodus is an average of all extrapolated dates when each human civilization claimed to begin. When accepted by nations across HIA, the Day of Exodus was established to be exactly 1000 years in the past. All subsequent years after that point in time got designated as After the Exodus (AE), and anything before that point was accounted for in negative numbers and designated as Before the Exodus (BE). This is why some cultures that claim to be older then others have historical accounts that date years Before the Exodus.
Federal Time System
Federal time system is based on an ancient cave painting that allegedly described the the time of humanity’s Ancient Origin. This system is used in reference to interplanetary processes and is not related to orbital cycles of any specific planet in the Federation.
Standard Year (SY) equals 12 Standard Months (SM), and 360 Standard Days (SD)
Each planet of the Federation has local time that is used as a reference for describing specific planetary events.
For example, when planning project on planet Azor, federal clerk should describe its time span in both Federal Time Units (SY, SM, SD) and in Local Time Units, like Azor Year (AY), Azor Month (AM) and Azor Day (AD)
