The rounded length of Venus synodic circulation of 584 days multiplied by five are added to the dates B and C 5-65 times and 130; 195 and 260 times. The real length of synodic circulation of Venus is 583.921 394 days. Time intervals of 185,120; 68,900; 33,280 and 9,100 days are added to the number B. And again the upper mentioned multiplies of 584 days. The total of B and interval of 33.280 days is the same as the date C, in the Dresden Codex mentioned only by the dates of calendar circle – 1 Ahau 18 Uo.
  
The total of B and 68,900 or B and 9,100 days is forming next dates D and E. Their last day always falls on 1 Ahau from 260 day tzolkin, as stressed in the Codex table.

   The rounded length of synodic circulation of Venus multiplied by five is 2,920 days. They contain:
  5 times the length of synodic circulation of Venus
13 times the length of siderialal circulation of Venus
  8 times the length of tropical year
 
   2,920  days is the typical period when the siderialal and sinodical circulation of Venus meet the tropical year. In this time the planet sets or rises in the same place in the sky after 8 years.
 
   Venus visibility ephemerides are mentioned in the next Codex tables. Its synodic circulation length is written like five times /236 and 90 and  250 and 8 days/. These are comprehensible approximate values, because of the synodic circulation length of this planet is moving between 577 and 592 days.
 
236 days - Venus is in the eastern sky as a morning star
  90 days - Venus is around the upper conjunction with the Sun and not visible
250 days - Venus is in the western sky as an evening star
    8 days - the Venus is around the lower conjunction with the Sun and not visible
 
This specification is added to dates B and D five times.
 
   Dates B, C and D are concerning the moment of Venus first observation as a morning star after its lower conjunction with the Sun.
 
   Date E is concerning the moment of Venus first observation as an evening star after tens of days of invisibility because of its upper conjunction with the Sun.
 
B/ January 27, 727              The Venus is 8 days after the lower conjunction with the Sun. For   first time observed as a morning star in the eastern sky.
                                               The Venus rose at 5.39 am
                                               The Sun rose at 6.34 am
 
C/ March 10, 818                 The Venus is five days after its lower conjunction with the Sun. For the first time observed as a morning star in the eastern sky. 
                                               Venus rose at 5.36 am
                                               The Sun rose at 6.11 am
      
D/ September 17, 915        Venus is six days after its lower conjunction with the Sun. For the first time  observed as a morning  star in the eastern sky.
                                               Venus rose at 4.54 am
                                                The Sun rose at 5.49 am
      
E/ December 27, 751         Venus is 63 days after upper conjunction with the Sun. For the first time  observed as an evening star in the western sky.
                                               The Sun set at 5.42 p.m.
                                                The Venus set at 6.46 p.m.
 
There is a time interval of 2,200 days marked between dates A and B. It contains:
19 times the Mercury synodic circulation length  /115.877 484 days/
25 times the Mercury siderialal circulation length /87.968 581 days/
 6 times the tropical year /365.242 199 days/
2,200  days is the typical period when the siderialal and sinodical circulation of the Mercury meet the tropical year. In this time the planet sets or rises in the same place in the sky after 6 years. The similar cyclical regularity was observed by the Mayan astronomers about Venus, with a period of 2,920 days. The dates A and B are marking the moments when the Mercury was to be found in a close approach of the maximal western elongations from the Sun. The D date concerns the maximal eastern elongation. Only in those positions around the maximal elongations is the planet visible not long before the sunrise or shortly after the sunset.
 
A/ February 4, 733               The Mercury is to be found in western elongation with angle distance 26.47 degrees from the Sun.
                                               The Mercury rose at 4.53 am
                                               The Sun rose at 6.32 am
                                               The maximal western elongation of 26.73 degrees was on January 31, 733. The difference between determined and real elongation is 0.26 degrees.
B/ January 27, 727              The Mercury was in western elongation with angle distance 25.5 degrees from the Sun.
                                               The Mercury rose at 4.55 am
                                               The Sun rose at 6.34 am
                                               The maximal western elongation of 26.07 degrees was on January 21, 727. The difference between determined and real elongation is 0.57 degrees.
D/ September 17, 915        The Mercury was in eastern elongation with angle distance 25.05 degrees from the Sun.
                                               The Mercury set at  7.10 p.m.
                                               The Sun set at 5.57 p.m.
                                               The maximal eastern elongation 25.12 degrees occurred just few hours later.
                                               The autumn equinox.
 
   In all three determined elongations the Mayan astronomers have made an average mistake 0.3 degrees less than reality. It is so slight difference that it can’t have been discovered.
 
E/ December 27, 751         The conjunction of Venus, Mercury and Jupiter. The position of planets is expressed in degrees of geocentrical ecliptical coordinates:
                                               The Mercury 295.489
                                               The Venus 294.289
                                               The Jupiter 294.987
   The time interval 2,200 days between A and B dates contains 74.5 times the length of synodic circulation  of the Moon /29.530 588 days/.
 
A/ February 4, 733                         The fullmoon
B/ January 27, 727                      The newmoon
