What does the Tzolkin calendar consist of in terms of days?

The Tzolkin calendar is a key component of the Mesoamerican calendar system, particularly associated with the Maya civilization. It is specifically composed of 260 days and is used for various ceremonial and agricultural purposes. This cyclical calendar features 20 distinct day names paired with 13 numbers, creating a cycle of 260 unique day combinations. This structure emphasizes the importance of certain periods, particularly in relation to rituals, harvests, and other significant cultural events.

In contrast, the other options reference different time measures. For instance, 365 days corresponds to the Haab' calendar used by the Maya, which is another aspect of their calendrical system that tracks the solar year. The mention of 52 years refers to a larger cycle known as a Calendar Round, which combines both the Tzolkin and Haab' calendars. Lastly, the term "1 year" could imply a singular reference to either calendar, but does not specifically address the unique day count of the Tzolkin. Thus, recognizing the specific duration of the Tzolkin as 260 days is essential to understanding its role within Maya timekeeping and cultural practices.
