The Enciclopedia de México notes that certain practices in connection with the celebration of the dead seem “to preserve elements of the Indian ceremonies of the months ochpaniztli and teotleco, during which cempasúchil flowers and corn tamales were offered to the manes [souls of the dead] at a time of the year in which the harvest had just been gathered ​ — at the end of October and the beginning of November. ”
„ Enciclopedia de México ” märgib, et mõningates surnute mälestamisega seotud tavades paistab olevat „säilinud kuudele ochpaniztli ja teotleco omaseid indiaanitseremooniad, kus manes’itele [surnute hingedele] ohverdati oktoobri lõpus ja novembri alguses saagikogumise lõppedes cempasúchil’i taime õisi ja rahvuslikku maisirooga tamale’t ”.
