Сколько дней было в календаре майя?
The "tzolk'in" (in modern Maya orthography; also commonly written "tzolkin") is the name commonly employed by Mayanist researchers for the Maya Sacred Round or 260-day calendar. The word "tzolk'in" is a neologism coined in Yucatec Maya, to mean "count of days" (Coe 1992). The various names of this calendar as used by precolumbian Maya people are still debated by scholars. The Aztec calendar equivalent was called "Tonalpohualli", in the Nahuatl language.
