While this is not a book review of “Calendars and Years II: Astronomy and Time in the Ancient and Medieval World”, it is definitely worth having a thought about what it says regarding our topic. According to Gerardo Aldana, Professor for Ethnic Studies at the University of California Santa Barbara, there might be yet another problem with the Mayan calendar, apart from it simply switching to a new b’ak’tun.
For the background: To adjust the Mayan calendar with our today’s Gregorian calendar, the so called GMT correlation constant is used. GMT is the abbreviation of the three Mayanist’s last names Goodman, Martinez and Thompson, that calculated this constant. Later Floyd Lounsbury used the Venus Table in the Dresden Codex to prove the GMT correlation constant. In this Venus table, dates are correlated with the movement of Venus. You can see an example for such a correlation at famsi.org.
Gerardo Aldana now states that conversion with the Venus Table is not as irrefutible as many think. According to him, it could easily be true, that therefore the GMT constant is slightly off. And since we are talking about a complicated calendar system, we could talk about 50 or even 100 years.
This leaves the questions: When would the doomsday really be? 2062? 2112? Or has it already been in 1962 and nobody realized of it?
