This last mystery of the Mayan calendar has finally been solved!

The Maya civilization remains among the most mysterious civilizations of our past. We know that astronomy played an important role in Mesoamerican culture, according to many remains found during excavations. In particular on the two main calendars: one sacred, baptized Tzolk’in, which is based on 20 cycles of 13 days, and the other, Haab’ baptized, of 365 days. The two intersect every 52 years, and are associated with the Long Count, a 20-base dating system.

But if these two calendars are deciphered, some of the cycles they contain are still a mystery. Like the number of 819 days, which was just decoded by a team fromCambridge University. Some of the monuments already contain inscriptions evoking this cycle, and also include four ColorsColors associated with the main trends.

A number associated with the appearance of the planets

This number has been previously analyzed by many scientists, and has already been imagined as related to the combined periods of the planets of the solar system, which mark when the planet returns to the same configuration with the Earth and the Sun. But the idea only worked for Mercury, which has a synodal period of 117 days, or 1/7 of its 819 days.

The researchers then solved the question by extending the computation period to 20 times 819 days, a maneuver in agreement with The fact is that the Mayans used the 20 base positional numbering system. Different planets.

For example, for a Mars period of 780 days, 21 periods correspond to 20 cycles of exactly 819 days. Likewise, for the Synodal period JupiterJupiter 399 days, 39 times this period corresponds to 19 times 819 days. Ultimately, all planets are visible toeyeeye Nu from the solar system is included in this system, which makes it possible to verify its authenticity AccuracyAccuracy.
