### Mayan Seasonal Almanac

Four double calendar round periods, each 37960 days, have be scaled into the raw seasonal almanac data. Four new doors to Mayan calendar building offers two calendar round periods in parallel and likely in series by first considering 260 day lunar, 520 day eclipse and 364 solar cycles.

### Four two-calendar-rounds

Four two-calendar-rounds offers a third level of the text. The Madrid Codex offers a more complex nine-calendar round context scaled to LCM 260, 360 = 4680 = 18(260) = 13(360) = 6(780), LCM 365, 360 = 9 CR, LCM 365, 260 = 1 CR, LCM 365, 584 = 2920 = 8(365) = 5(584), LCM 365, 780 = 3 CR and LCM 365, 585 = 42705 = 117(365) = 73(585.)

Fourth, on level three of the Drsden and the Madrid codicies, LCM (a, b, c) combinations of 260, 360, 364, 365, 584, 585 and 780 offers an interesting distribution: 2340 (1), 4680 (2), 5460 (1), 16380 (2), 26280 (1), 32760 (3), 2-CR (1), 3-CR (1), 6-CR (2), 7-CR (1), 9-CR (2), 14-CR (2), 18-CR (6), 21-CR (1), 42-CR (2), 63-CR (1), and 126-CR (3).

Fifth, on level three of the Dresden and Madrid, LCM (a, b, c, d) combinations of 260, 360, 364, 365, 584, 585 and 780 offers another interesting distribution: 32760 (1), 6-CR (1), 9-CR (1), 14-CR (1), 18-CR (5), 21-CR (2), 42-CR (2), 63-CR (2), and 126-CR (7),

with CR = 18980 DAYS attests to Mayan math methods.

### Madrid and Dresden Calendar Round texts attest each other

The Madrid Codex has long been known as a Mayan calendar round text. Cyrus Thomas suggested in 1900 that Madrid quotients be scaled by 360. The following link scales Dresden Codex quotients by 400 implying that Madrid 3650 and 4680 data points were scaled by lunar, earth, Venus and Mars cycles and 3-calendar and 7-calendar rounds per: LCM (260, 360) = 4680 = 18(260) = 13(360) = 6(780), LCM (365, 364) = 7 CR, LCM (365, 260) = 1 CR, LCM (365, 584) = 2920 = 8(365) = 5(584), LCM (365, 780) = 3 CR, and LCM (365, 585) = 42705 = 117(365) = 73(585). http://planetmath.org/mayanseasonalalmanac

What is new related to the Dresden Codex is that several Madrid data points were scaled to lunar, earth, Venus and Mars cycles and explicitly to Jupiter (399, 1432) per long count numbers:

4.4.4.4 = 30824 = 76(399) = 7(4332)

6.6.6.6 = 45486 = 114(399)

7.7.7.7 = 53067 = 133(399)

8.8.8.8 = 61648= 152(399) = 14(4332)

11.11.11.11 = 83391 = 209(399)

13.13.13.13 = 98553 = 247(399)
