The calendar was so perfect that, when Europeans arrived and knew it, they realized that their Julian[1] calendar was wrong and adjusted their calendar to ours, and called it Gregorian[2], since it was Pope Gregory XIII who ordered the reform to the Julian calendar in 1582.
"The origin of the prehispanic computation has been traced from its Olmec roots. Remember that the word Olmec derives from two words: ollin: movement and mecatl: rope (mecate), in reference to rope measurement; thus the measure of movement or the movement measure. This means that the Olmecs were probably known as cosmic movement measurers and its expression in geometric shapes...". (Ma. Elena Romero M. 1988)
Mexico possessed 75% of the planet's biodiversity. Our ancestors knew the medicinal uses of food, utilities, surprisingly almost all plants, minerals and animals; which inter alia allowed them to develop one of the perfect and ancient medicines of the world, which has survived to date. The Codex de la Cruz-Badiano[3] (1552), the amazing cranial trepanning found in burials, the massagers, those using plants (yerberos) and healers, is testimony of the permanence of this millenary wisdom that has resisted disappearing. It can be stated that global Pharmacology[4] foundations were built on contributions from three civilizations: China, India and Anahuac. To appreciate the complex and sophisticated knowledge ancient Mexicans had

- ↑ The Julian calendar, a reform of the Roman calendar, was introduced by Julius Caesar in 46 BCE.
- ↑ The Gregorian calendar, also known as the Western calendar or the Christian calendar, is the internationally accepted civil calendar. It was introduced by Pope Gregory XIII, after whom the calendar was named, by a decree signed on 24 February 1582, a papal bull known by its opening words “Inter gravissimas”. The reformed calendar was adopted later that year by a handful of countries, with other countries adopting it over the following centuries. The motivation for the Gregorian reform was that the Julian calendar assumes that the time between vernal equinoxes is 365.25 days, when in fact it is about 11 minutes less. The accumulated error between these values was about 10 days when the reform was made, resulting in the equinox occurring on March 11 and moving steadily earlier in the calendar. Since the equinox was tied to the celebration of Easter, the Roman Catholic Church considered that this steady movement was undesirable.
- ↑ The Codex de la Cruz-Badiano or Libellus de Medicinalibus Indorum Herbis (Latin for "Little Book of the Medicinal Herbs of the Indians") is an Aztec herbal manuscript, describing the medicinal properties of various plants used by the Aztecs. It was translated into Latin by Juan Badiano, from a Nahuatl original composed in the Colegio de Santa Cruz de Tlatelolco in 1552 by Martín de la Cruz that is no longer extant. The Codex is also known as the Badianus Manuscript, after the translator; the Codex of the Cruz—Badiano, after both the original author and translator; and the Codex Barberini, after Cardinal Francesco Barberini, who had possession of the manuscript in the early 17th century.
