The Mayan writing system, a complex blend of logograms and syllabic signs, was used to record history, astronomy, and religion. Developed over centuries, it flourished in Mesoamerica from 2000 BCE to 1500 CE, leaving behind intricate hieroglyphic texts on stone monuments, ceramics, and bark paper codices. Mayan calendars were sophisticated tools for tracking time and guiding society. The Long Count measured vast time periods, while the Haab' and Tzolk'in calendars regulated agricultural, religious, and personal activities. These systems showcase the Mayans' advanced understanding of astronomy and mathematics.
