Below is a chart that outlines the basic structure of the calendar. There are nine units of time in the Earth Epic Calendar. Three are categorized as the Epic Time Scales, while the remaining six are categorized as Calendar Time Scales.
The Earth Epic Calendar gives the option of tracking time by either Quarters or Moons (lunar months). With Quarters, the year is divided into four roughly equal quarters tied to the year. Moons are tied to the lunar cycles, which don’t fit accurately into the solar cycle.
