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 menyebutkan bahwa praktek - praktek tertentu sehubungan dengan perayaan orang mati tampaknya ” melestarikan unsur - unsur upacara Indian pada bulan ochpaniztli dan teotleco, ketika mereka mempersembahkan bunga cempasúchil dan tamale (semacam kue kukus) jagung kepada manes [jiwa orang mati] pada saat panenan dikumpulkan ​ — yakni akhir bulan Oktober dan awal bulan November ”.
