This calendar was created as a pagan representation of the calendar year to keep track of dates and times. Each of the 4 quarters of the year contains 91 days with a final day at the end of the year representing the winter solstice and the closing of the tropical year. The structure of the calendar is the same as the World Calendar. I marked the pagan celebrations as close as I could to the actual solstice and equinox dates, but due to the small shift in time from earth's orbit not being exactly 365 days the precise day of the astronomical observation may be 18 hours off of the celebration. It's important to remember that these are celebrations represented not only by astronomical precision but also by the spirit of the holidays they represent. One full procession of earth (~25772y) is split into 12 ages making each age roughly 2148y. The year is based on the representative age and each age represented by a different zodiac. I use the sidereal zodiac for yearly representation among the celestial because they are constant compared to the tropical that moves with the procession of the earth. You can think of the year as the sidereal representation and the months/celebrations as the tropical representation. The 0 degree location (right ascension) was chosen as the star Spica in the Virgo constellation, not only because it is a bright star on the horizon of ecliptic plane but because of Virgo's representation as a woman to birth the ages. The binary star Spica itself happens to be in the shape of an egg. With Spica being our start point where the earth is in alignment with the sun on the spring equinox we are currently in the age of Aries-y955. Each age follows the procession of the earth and the direction in which the North Pole is pointed. It should be noted that while the leap day is added every 4 years the leap skip is on the 128th year unlike the gregorian calendar that skips a leap year every 100 years. The calculations for the planet locations in the planetary map were computed using both the NASA JPL website and the Stjarnhimlen website.
Why Spica? Spica is a visible star that sits on the ecliptic plane in the Virgo constellation making it perfect for a planetary coordinate system. The current Equatorial/Ecliptic coordinate system relies on the alignment of the earth with the sun on the northern hemisphere spring equinox. As you may know from the procession of the earth this is not a great marker because the equinox does not remain constant over long periods of time. So over enough time the right ascension and declination will drift leading to the need to define a new epoch for astronomical measurements. This coordinate systems comes in both geocentric and heliocentric models. The next step up from those models is the Galactic model that relies on an imperceptible Galactic Center. So while the Galactic coordinate system is steady compared to the Equatorial/Ecliptic it does so at the expense of being able to find the galactic center of our galaxy. The proposed Spica point is the "best of both" sweet spot that has the relative stability of the Galactic model while having the measurement visibility of the Equatorial/Ecliptic model. I've given the coordinate system the name Astraeal to pay homage to the ancient Greek star-maiden.
