Editing Aztec calendar (section)

==Reconstruction of the Solar calendar==
For many centuries scholars had tried to reconstruct the Calendar. A widely accepted version was proposed by Professor {{lang|es|Rafael Tena|italic=no}} of the {{lang|es|[[Instituto Nacional de Antropología e Historia]]}},<ref>The Mexica Calendar and the Chronography, Rafael Tena. INAH-CONACULTA. 2008</ref> based on the studies of {{lang|es|Sahagún|italic=no}} and {{lang|es|Alfonso Caso|italic=no}} of the [[National Autonomous University of Mexico]]. His correlation argues that the first day of the Mexica year was February 13 of the old [[Julian calendar]] or February 23 of the current [[Gregorian calendar]].
Using the same count, it has been the date of the birth of {{lang|nci|Huitzilopochtli}}, the end of the year and a cycle or "Tie of the Years", and the [[New Fire Ceremony]], day-sign {{lang|nci|1 Tecpatl}} of the year {{lang|nci|2 Acatl}},<ref>Crónica Mexicayotl, Fernando Alvarado Tezozomoc p 36</ref> corresponding to the date [[February 22]]. A correlation by independent researcher Ruben Ochoa interprets pre-Columbian codices, to reconstruct the calendar, while ignoring most primary colonial sources that contradict this idea, using a method that proposes to connect the year count to the vernal equinox and placing the first day of the year on the first day after the equinox.<ref>Azteca/Mexica Calendar Correlations: the Good, the Bad, and the Completely Useless, Itztli Ehecatl. http://www.calmecacanahuac.com/blog/calendar/aztecamexica-calendar-correlations-the-good-the-bad-and-the-completely-useless/. 2015</ref> 

In this regard, José Genaro Emiliano Medina Ramos, a senior native nahua philosopher from [[Calpan|San Lucas Atzala]] in the state of Puebla, proposes a multidisciplinary calendar reconstruction in náhuatl (‘centro de Puebla’ variant) according with his own nahua cosmosvision;<ref>{{Cite book |last=Medina Ramos |first=José Genaro Emiliano |url=https://filosofia.buap.mx/sites/default/files/Libros%20electr%C3%B3nicos/Antropolog%C3%ADa/calmecac%20dig.pdf |title=CALMECAC Tradiciones y pensamiento del pueblo de San Lucas Atzala |publisher=BUAP |year=2012 |edition=Digital |location=Puebla, México |language=Spanish}}</ref> and relying precisely on Ochoa's smart correlation and on Tena's presuppositions as well. His proposal was translated to Spanish and English, and codified as an academic webpage in 2023.<ref>{{Cite web |last=phk |first=phk |date=2023-01-01 |title=tonalamatlahtolcuepalli: tlahtolcuepalli itech tonalamatl gregoriano itech mexihca tonalamatl / Convertidor calendario gregoriano -> sistema calendárico mexica / Gregorian calendar -> mexica calendrical system converter |url=https://sites.google.com/view/tonalamatlahtolcuepalli/ |access-date=2023-01-27 |website=tonalamatlahtolcuepalli |language=en-US}}</ref>
