2. 13~XX
theAbysmal 13~XX follows the structure of the Mayan tzolkin Calendar, although its application differs in several respects.
the tzolkin Calendar has 2 cycles: the first of 13 numbers (1~13) and the second of 20 glyphs, set in a particular progessive order. theAbysmal Calendar represents the glyphs with the Roman Numerals I to XX, such that calendar users may assign glyphs to them as best suits their cosmological preference.
The numbers and glyphs assigned to each Day progress from the top left of the diagram downwards, following the columns from left to right. They progress as follows:
1~I, 2~II, 3~III, 4~IV, 5~V, 6~VI, 7~VII, 8~VIII, 9~IX, 10~X, 11~XI, 12~XII, 13~XIII, 1~XIV, 2~XV, …, 9~XVI, 10~XVII, 11~XVIII, 12~XIX, 13~XX, 1~I, 2~II, …
Each number~glyph combination coincides with each of the 365 Days of theAbysmal Solar Year, however, they do not coincide with the Leap Year Day.
These 2 coincident progressions further break up the division of the Days of the Year into periods of 4, 5, and 13. The Calendar groups these further into measures of 52 and 65 Days. This finds greater significance in section 4. Calendar Synchronicity & Symmetry.
