The Aztec New Year, also known as Año Nuevo Azteca or Mexica New Year, is celebrated by Nahua communities in Mexico on March 12. Major festivities occur in locations such as Mexico City, Huauchinango, Naupan, Xicotepec, and Zongolica. The celebration begins on the night of March 11, featuring ceremonial dances, songs, and traditional drum music, with dancers adorned in colorful attire and quetzal feather headdresses. Customs include offering seeds, burning ritual candles made from ocote pine resin, and setting off fireworks. The festivities culminate at sunrise on March 12 with the burning of a flag representing the old year and the welcoming of the new year by blowing conch shells. Various educational and cultural events are organized around this date to promote understanding of Aztec heritage and traditions. Small-scale celebrations also take place in some Nahua communities in the United States, particularly in Los Angeles and Houston.
