Numbers

Ancient Egyptians realized that 365.25/365 = 1461/1460. Period 1460 years was called Sothis (Sirius).
Similarly Mayans has found that 365.2422/365 = 1508/1507. So, 1507 tropical years last integer number of days:

1507*365.2422=1508*365=550420 days.

Number 550420 has these divisors:

550420 = 2² *5 *13 *29 *73.

Mayan selected 13 (13 god numbers) and 20 (20 god days). Their combination 13*20 = 260 days was called "tzolkin".
Conjunctions of Earth with Mars repeat with period 780 days: 780 = 2² *3 *5 *13 (3*tzolkin).
Integer period of Earth, 365 days: 365 = 5 *73.
Mayan used the prime divisors (2,5,13,29,73) completed by other small numbers (3,7,9,...) for deriving of cycles.

Tzol'Kin

Sacred cycle of Mayans and Aztecs, z=260 days. It is probably certain "quantum" for synodical periods of inner planets and moon.
Tzol'Kin - Correlation

Tzolkin is equal to third of synodical period Earth-Mars and to 3/4 of ecliptic year.
50*z make 3 orbital periods of Jupiter, (so 600*z make Babylonian period 427 years).
Tzolkin is also equal to c. 4/9 of (V,E) and 19/2 of sidereal moon.

259.52061 days: (V,E)*4/9 = 583.92138 days *4/9
259.55578 days: 9.5*L = 9.5*27.321661 days
259.95536 days: 1.5*J/25 = 17.7929747 years/25 = 0.711719 years
259.965 days: Ey*3/4 = (E,Ln)*3/4 = 346.620 days *3/4
259.9787 days: (E,R)*1/3 = 779.9361 days *1/3

Stable resonance (-V/3, E, R/2) has period 129.94 days, i.e. z/2.

Tzol'Kin - Sequence

Some configurations (alignments) of the planets Venus-Earth-Mars follow each other
exactly with the period of Tzolkin:

9.12.2002 + TZOLKIN => 26.8.2003 + TZOLKIN => 12.5.2004

13.5.2009 + TZOLKIN => 28.1.2010 + TZOLKIN => 15.10.2010

Calendar round

The smallest common multiple of tzolkin (260-days) and haab (365-days):

nsn(365,260) = 18980 days = 52 Haab (51.965 years).

Approximately 52-year cycle seems to be combination of 4-year period of Venus with 13 year period of Mercury.
Period 13 years

Mercury returns to the same (Earth) season with period c. 13 years (mean value 13.006 years, Smith,Bruce, 1972).
E.g. 1990 and 2003 begin with these conjunctions:
9.1.1990, 3.5.1990, 8.9.1990, 24.12.1990, 14.4.1991, ...
11.1.2003, 7.5.2003, 11.9.2003, 27.12.2003, 17.4.2004,...
During 41 conjunctions Mercury-Earth Mercury completes 54 (i.e. 41+13) orbits. Mayan megalith with 43 stones (2 reference points)?

12.9 years: summer thermal cycle (Hudson Valley)
13 years: frequency of storms (Aniol, 1952)
13 years: transits of Mercury over Solar disc
13.006 years: 54 M; repetition of Merkury ephemeris (Smith and Bruce,1972)

Calendar round (18980 days) differs from 52 orbits of Earth (tropical 18992.6 days, sidereal 18993.3 days) by c. 12.6-13.3 days.
To keep exact length of year, c. 13 day corrections are necessary every 52 years, i.e. 1 day every 4 years.
Half period of 65 conjunctions Venus-Earth:
65*(V,E)/2 = 65*583.9214/2 = 18977.45 days (51.95741 years).

(S,U) = 45.364 years: 45.364/126.10 = 9/25, 45.364/70.854 = 16/25
51.63 years: 13/5 (J,S)

Aztecan century

Two calendar rounds:

13*2920 days = 8*4745 days = 2*18980 = 37960 days (104 years)

46*260 days = 65*584 days = 104*365 days = 37960 days (104 years).

Conjunctions M-V-E occurred in years (precision 40°): -3631.23, -3527.18, -3423.41, -3319.35, -3215.28, -3111.56, -3007.46, -2903.78, -2799.70, -2695.97, -2591.91, -2488.14...

Inequality (E,Ln,-R/2)= (R/2,Ey/1)= (1.88089/2, 0.94899/1) = 104.4 years.
From (Ln/4,-E/5,R/9) = 0 follows (E,-R,Ln/8) = 26 years. So (Ln/4,2*(E,R)) = (4.65, 4.27) = 52 years.
Period of 65 conjunctions Venus-Earth:

65*(V,E) = 65*583.9214 = 37954.9 days (103.91482 years)

Also inequality (J/13, S/32)= 104.0 years, i.e.(5/J-4/S)/(4/J-5/S) = 5.97122/3.49995 = 1.706; (12/7=1.7143).

Long count

Raster of dates

Mayan syntax of dates makes possible to observe accuracy of conjunctions of Earth (E) with Mars (R) and lunar line of nodes (Ln). These conjunctions E-Ln-R frame certain raster with period 12 tzolkin, i.e. 3120 days (8.542 years).
In the following schema the rows step with period of conjunctions Earth-Mars. Period 13 tun (18 tzolkin) is highlighted (bold).

Period Y represents accurately value of 12 tzolkin in the Mayan calendar.

Y = 12z = 12∙260 days = 3120 days (8.5413 years)

Mayan syntax of dates allows us to monitor the accuracy of conjunctions Earth (E) with Mars (R) and node line of the Moon (Ln). Conjunction E-Ln-R creates a kind of grid with a period 12 tzolkin.

The following diagram lines proceed with periods of conjunctions Earth-Mars. Periods of 13 tons (18 tzolkin) is highlighted in bold.

Zero

Number zero may appear in mayan dates. E.g. 10.11.4.0.14 = 10.11.3.18.14.

Congruences

We can test connections of Mayan dates with help of congruences (remainder classes).
E.g. the following dates are congruent according to module 260 days (tzolkin):

Mayan date      D [days]   D/260   D mod 260]
 -------------------------------------------
 9.16. 0.13.17  1411477   5428.7577    197
 9.16. 4. 6.17  1412777   5433.7577    197
 9.16.12. 5.17  1415637   5444.7577    197
 9.17.19.13.16  1425516   5482.7538    196

Katun

Mayan katun, 20*18*20 days = 7200 days (19.7125 years) reminds cycle of conjunctions (J, S) = 19.86 years. Three katuns (ie. 59.14 years), cover approximately 37 conjunctions of V-E.

But it's - in all probability - entirely something else!? Foundation of the Mayan calendar "long count" is built of Katuns... (Also e.g. dates 9.10.16.10.13, 9.11.16.10.13, ie. dates of "cosmic monster" from Yaxchilan, differ by katun.).

When observing the conjunction of Moon and Jupiter perceive cycle 9 * (E, J) = 3590 days = 9.83 years. Average duration of two such cycles 2 * 9.83 = 19.66 years differ by Maya Katun only about 20 days (1 tun).

In the following outline approximate dates of conjunction of the Sun-Earth-Moon-Jupiter are listed. (A similar sequence - only about 14 days shifted - forms also the conjunctions of the Sun-Earth-Moon-Jupiter). We deliberately chose the sequence that ends at the time the strongest earthquake observed - May 22, 1960 (Valvidia in Chile):

     1891,60 1891 Aug  4 AD	1891,599	E: 313,7 J: 341,6 Moon: 134,7
   * 1901,46 1901 Jun 15 AD	1901,461	E: 265,5 J: 278,3 Moon:  75,5
     1911,25 1911 Mar 29 AD	1911,247	E: 189,4 J: 218,5 Moon:   0,4
     1921,11 1921 Feb  6 AD	1921,109	E: 138,7 J: 163,1 Moon: 305,7
     1930,97 1930 Dec 18 AD	1930,971	E:  87,3 J: 104,9 Moon: 252,9
     1940,84 1940 Oct 30 AD	1940,838	E:  38,1 J:  41,1 Moon: 216,2
     1950,62 1950 Aug 13 AD	1950,623	E: 321,2 J: 332,1 Moon: 142,3
   * 1960,40 1960 May 24 AD	1960,403	E: 244,2 J: 267,2 Moon:  56,1

Directions of conjunctions move in each step (with a duration of 9.83 years on average) about 60 dg, ie after 6 steps (3 Katun) returns to the same place.

Other aproximations:

19.65754 years: 18*(J,E)
19.6961 years: 3*[J,S/2] = 3*6.56536 years (tropical)
19.7027 years: 3*6.56757 years = 3*243 years/37
19.7105 years: 16*1.2319 years =177.39/9=11.0951*16/9
19.7111466 years: [J, S/2] = [(J,S), (5J,2S)] = [19.86,2650]
19.71403 years: 5*15.771227 years/4
19.71595 years: 3*[J,S/2] = 3*6.57198 years (anomalistic)
19.725 years: 3*(E/4,M) = 3*6.575 years

Application of Long count

Earth(E), Mars(R), node line of Moon(Ln) and Venuše(V) repeat the same configuration with the period 6Y:

6∙Y = 72 tzolkin= 72∙260 d= 32∙585 days= 18720 days (51.25 years)

The difference of the first two "serpent numbers" 10.11.5.14.5, 9.17.8. 8.5 makes 32Y:

32∙Y= 192 tzolkin = 10.11.5.14.5-9.17.8. 8.5= 1521285-1421445= 99840 days (273.3 years)

Accuracy of Long count

It seems natural to consider as the basic points of the Long Count moments of conjunctions Earth with Mars.

Accuracy of long count

With regard to conjunctons E-R: conjunctions (E,R) do not last 3*260 days, but at average a less

(E,R) = 2.1353487 years, i.e. 779.9361 days

Difference 0.0639 days/780 days, i.e. 1 day/12207 days (33.42 years), c. 4 days/130 years.
Mayan tropical year 365.2422 days is more exact: today value is 365.24219879, difference 0.00000121 * 86400 s / year,
i.e.. 1 s/ 9.565 years (S.M.Brisbin 26.3 s/day?!).

Period 819 days

Synodical period (R,J) is c. 816.43 days (2.2353 years).
One of the periods of atlantic oscillation makes c. 27 months, i.e. 2.25 years.
Alignments E-M-R (conjunctions M-E-R) repeats with period c. 820 days (2.25 years);
7*(M,E) = 7*115.87 = 811.1 days, 8*(M,R) = 8*100.88 = 807.0 days.
Nodal (draconic) months: 30*27.1222=816.37 days.
Similar configurations of E-M-R occur with period 2*J = 25*Ey (c.23.725 years = 10.5*2.2595 years).
819 days = 7*9*13 days; ( Number 9 control cycle of "lords of nigths".)
7*13 days = 91 days (364/4),
9*13 days = 117 days, approximation of (M,E)=115.87 days
E.g. see 9.15.19.1.1, 9.15.19.14.14, 9.16.1.0.0 (stela 11, Yaxchilan).

Natural month

Tun-Uc

Calendar with 28 days cycle of ‘natural months‘.
Sometimes it appears to be more favourable to divide year to 13 months. Orbital period of Venus is approximately 8/13 of our year. For observer on the Earth, every (V,E), i.e. c. 583.92 days, Venus passes Earth (in direction of Earth motion). Moon passes this place (against Venus direction) every c. 29.53 days. So, with regard to Venus, orbital period of Moon is little bit shorter.
It holds: ((E,L),(E,V)) = (29.53, -583.92) = 28.11 days.

Tzotz tun

Calculational year, bat cycle, 364 days = 4*91 days = 13*28 days.
Mayan add k*364 days (Dresden codex, F 45) to date 8.17.11.1.10, k=(2-5),10,15,40,60,80.
Multiple 20*364= 7280 days= 19.932 years is the period of symmetric configurations, alignment of axes J-S and U-N.

Other periods

Period 65 days

Greatest common divisor of periods (V,E) and (E,R) is c. 195 days (780/4 = 585/3 = 195), i.e. 3*65 days.
Mayans derived some data from multiples of 65 days:
65 = 5*13 (=780/12 = 585/9 = 260/4). Also (V,E/2) = 975.3 days = 5* 195 days = 15*65 days;
11 synodical months (324.83649 days) is c. 325 days = 5*65 days (177+148 days).

Period 2200 days

Period 2200 days (6.023 years) is a common multiple for M and (M,E) M/(M,E) = 19/25 (Bohm&Bohm).

Period 3120 days (12 tzolkin)

Ecliptic year and conjunctions Earth-Mars are synchronized with period Y = 4*(E,R) = 9*(E,Ln), i.e. 8.5413 years (c. 3120 days). Let us note, that 12*z = 12*260 days = 3120 days.
E.g. 10.11.5.14.5 - 9.17.8. 8.5 = 1521285 - 1421445 = 99840 days = 32*3120 days (first two "serpent numbers").

Period 18720 days (72 tzolkin)

Period of alignment V-E-Ln-R: Earth(E), Mars(R), lunar line of nodes(Ln) and Venus(V) repeat the same configuration with period:
6*Y= 72 tzolkin= 72*260 d= 32*585 days= 18720 days (51.25 years).

Period 130 years

Period Y is approximately 16/15 of 8-year period. Common multiple (15*8.54,16*8.00 years) equals to beats (8.0, 8.542), i.e. makes c. 125-130 years.
Aztecan century 37960 days (104 years) contains 65 conjunctions V-E. But conjunctions M-E in the meantime shift, by c. 0.587 (M,E).
Did Mayans try to correct this deviation?
189800 days =10*18980 days =1637.9366*115.8775 days (520 years).

Period Baktun

Period 20*18*20*20 = 144000 days, i.e.394.25 years.

394.3 years: 1 baktun= 20*katun = [427.07, 5125] =5125/13 (Mayan cycle)
394.5 years: 11*(S,N) = (9J,U)
400 years: secular period of solar activity (Vitinskij)
400 years: Link’s period of solar activity derived from visibility of comet
400 years: climatic cycle (Milankovic)

Baktun do not coincide with multiples of period Y (12*11960 = 46*3120 = 143520 days) nor with multiples of ecliptic year (416*(E,Ln) = 416* 346.6 days = 144186 days).

Period c. 144240 days is common multiple of conjunctions of inner planets:

144240 days = 185*779.68 =210*686.86 =247*583.97 =642*224.67 days.

Such duration has e.g. interval 9.19.5.7.8 - 10.19.6.1.8 (Bohm&Bohm).

     13.  4 Ahau

Origin is assumed to be at the beginning of 13 baktun (4 Ahau).

Baktuns step through seasons 4*394.25=1577 years ().

Period 3742 years

Period V-E-Ln-R and calendar round differ by one tzolkin. Common multiple:

1366560 days = 72 calendar rounds = 73 period V-E-Ln-R
1366560 days = 2⁵* 3²* 5* 13* 73 days = 5256 tzolkin= 3744 haab (3741.44 years)
1366560 days = 117* 32 haab = 2340*584 days = 1752*780 days.

Period 5125 years

Mayan combined (orbital?) period c. 394 years and (Babylonian) period (of planetary configurations) into cycle 5125 years.

5125 years = 12427.1 years = 13394.23 years

Period 13 baktun, 12 Babylonian cycles.
1872000 days = 7200 tzolkin = 600 *Y = 260 katun.

Various recurrence of planetary positions are observable with the period of 13 Baktuns...
