Calendar designed and utilized by the Commander, as part of his research and recording of the Chronicles II during his time on board the Ark, prior to the Armageddon Wars. The calendar is based on the flow of time in the Visionary Universe, which for purposes of comparison within the calendar system is referred to as the True Measure of Time, with other varied flows of time then listed as Contextual Measures of Time. The use of those terms are not meant to imply in any way that one measure is more accurate or correct than any other, simply that one had to be chosen as the defining measure and then others seen in comparison. The Calendar itself is unique from any other calendar based system on multiple fronts.
