Calendar A formal table of time measures based on the motions of the heavenly bodies. Where esoteric knowledge is intact, these cyclic motions and the periods they mark are inseparably connected with all other parts of the esoteric system. Nowadays, the original calendars having been lost and reconstructed for purely civil or ecclesiastical purposes, they have no other significance. But formerly they likewise indicated the courses of cosmic evolution and the succession of human races. The Surya-Siddhanta gives the number of revolutions of the planets in 4,320,000 years, among other such data; and the work itself claims to be the result of observation over an immensely long period, based on a knowledge of the mathematics underlying the cosmic and terrestrial cycles. This calendar or astronomical-astrological work claims to be the original production of the Atlantean astronomer and magician Asuramaya.
The Mayas of Yucatan had a calendar system, deciphered at least in part, that extended far back into the past. In this calendar we find not only the familiar cycles of the lunation and of the solar year, but others such as the synodical revolution of Venus, and exact periods of 250, 280, or 360 days. The Egyptians in their calendar time-measurements used three different years, one of which was a year of 365 days, adapted to the Julian year by a Sothic period of 1460 years. The lunar year of 12 lunations is one of immense antiquity, and formerly of almost universal usage, frequently combined with the solar year; and the lunar year is still used, with various systems of intercalation to adapt it to the tropical year.
