History: The Mayan calendar is one of the most sophisticated and precise time-division systems in human history. It is based on knowledge of Mayan cosmogony and their complex astronomical studies. The Mayan calendar formed the basis of the entire social, political and civil structure of the civilization. It established a time organization necessary for the development of their culture. Order responded to sacred rituals, harvest seasons and periods of war, which maintained the power of their empire. The calendar faithfully reflected the movements of the planets, eclipses and solar and lunar cycles, helping to make important decisions involving the future of civilization. Meaning: The calendar guided people’s lives from the moment they were born, and few things escaped its influence. The Mayan Calendar as an amulet offers protection and guidance, while reminding us of the importance of connecting with nature, for wisdom resides within us, handed down by our ancestors and present in our DNA.
