About the Calendar
The Ecliptian Calendar, also referred to as the Sunday calendar, is a 28 day month, 13 month year calendar, that spans 365 days between the current March equinoxes. The equinox events define a full orbit of the earth around the Sun as we perceive it. The calendar divides the year into months with equal days. The calendar also includes additional neutral uncounted days to mark the equinox event and a Leap Year day when applicable.
The 13 month calendar isn't a new concept . It gained popularity in the 1920s, and was used up through the 1980's unofficially at Eastman Kodak, however those calendars didn't revolve around any specific solar or cosmic event.

The Procession of the Equinox
The procession of the equinox is the alignment of the Earth to different star constellations as its tilted axis point slowly rotates over time. The constellational alignment is defined by the constellation that rises at the horizon on the March equinox (Solis Diem). It changes by 1 degree every 71.6 years taking 25,920 to complete. A full rotation through the constellations is referred to as a Great Year. The "Oblique Date" is the Great Day of the Great Year as we calculate the years since the planet's estimated existence.
Entering a new constellation takes 2160 years, referred to as Platonic Month. This is referred to as entering a "New Age". Many argue we have entered the "Age of Aquarius". It is theorized that the Great Sphinx was originally a Lion and was built to align with the constellation Leo. This allows the Sphinx to act like the arm of a giant celestial clock. This would also signify the age of when the great statue was created, as it would have align with the constellation Leo (The lion) when the sun rose on the equinox.
Galactic Rotation
The galactic year, also known as a cosmic year, is the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy. One galactic year is 230 million Earth years. If we divide the estimated age of the universe by this number we can derive the Galactic Year. The current agreed upon age is 61 .
