Day Symbols of the Maya Year is evocative book authored by Cyrus Thomas. The day symbols used in the Maya calendar system are examined in this book. By analysing the glyphs and symbols connected to every day in the Maya calendar, Cyrus Thomas illuminates the complex and sophisticated nature of the Maya calendrical systems. The Maya possessed a highly developed awareness of astronomical cycles and an elaborate calendar that included a religious and secular tally of days. In "Day Symbols of the Maya Year," Thomas offers insights on the religious importance of specific days, the way the Maya arranged organised time, and the relationship between the calendar and Maya society. It is a significant addition to our knowledge of Maya society and its calendrical systems and demonstrates the breadth of Cyrus Thomas's late 19th-century anthropological and archaeology studies.
