Some of you have asked about the 13 Moon calendar used by the Mayans.
The moon can be measured by various cycles.
The 28-day count is derived from the average lunar cycle. The synodical cycle, from new moon to new moon, is 29.5 days (this is what most lunar calendars are based on). The sidereal cycle, the measure taken from where the moon appears at the same place in the sky, is 27.33 days.
There is also an apsidal cycle, taken from the measure of when the moon's axis is tilted farthest from the Earth, which is 28 days.
Counting the year by 28-day moons, we have: 13 X 28 (+ 1 day out of time) = 365 days. A perfect formula!
The 28-day cycle is also the average of the female fertility cycle, often referred to as one's 'moon cycle.'
In actuality the moon goes around the Earth thirteen times a year. This means that the 13 Moon calendar is a genuine solar-lunar calendar which measures the Earth's orbit around the sun by the lunar average of 28 days. Thirteen perfect months of 28 days = 52 perfect weeks of 7 days = 364 days. The 365th day is called the Day Out of Time because it is no day of the week or month at all. This day, which falls on the Gregorian correlate date of July 25, is a day for forgiveness and for the artistic celebration of life and freedom.
The synchronization, or new year's date, of the 13 Moon calendar is July 26. This corresponds to the rising of the great star Sirius. This makes the 13 Moon Calendar a tool for harmonizing ourselves with the galaxy. |
