It really needed a broad view to be fully understood.
Researchers at Tulane University in Louisiana have solved the mystery of the 819-day calendar used by ancient Mayans. Using a 45-year span, the researchers were able to match the planetary cycles of all planets that might have been visible to astronomers of the civilization.has thrown up multiple calendars that were likely used by scholars of the time, but not all of them make sense in today's world.
Moreover, ancient glyphs have shown the calendar to consist of four parts and even boast a color-directional scheme, making the mystery even more intriguing. However, researchers John Linden and Victoria Bricker have cracked the purpose of the calendar by simply broadening their point of view.Instead of looking at the calendar over short periods of time, they used it for over 20 periods of 819 days each and found a pattern that emerged with regard to the synodic period of planets.
Moving further, the researchers found that Mars, with a synodic period of 780 days, exactly matches 20 cycles of an 819-day calendar, while Venus needs seven synodic periods to match five counts of 819. Going further, Jupiter takes 39 periods and matches 19 counts of 819, while Saturn has 13 periods in six 819-day counts.
The researchers state that instead of limiting their focus to just one or two planets, ancient Mayans created a large calendar system that could be used to predict the synod periods of all visible planets.
