Was the Beginning Day of the Maya Month Numbered Zero (or Twenty) or One?

"Was the Beginning Day of the Maya Month Numbered Zero (or Twenty) or One?" by Charles P. Bowditch is a scientific publication written in the early 20th century. This book delves into the complexities of the Maya calendar system, particularly focusing on the counting methods used to label the beginning days of their months. It examines whether the Mayans designated the initial day of the month as Day 0, 20, or 1, aiming to clarify a long-standing debate among scholars. In this detailed analysis, Bowditch reviews evidence from the Dresden Codex and various inscriptions to explore the Maya's counting methodology. He presents arguments supporting Goodman's theory that the Maya month began with Day 0 or 20, rather than Day 1. By referencing specific examples and calculations from the codex, Bowditch concludes that the evidence leans towards the understanding that the Maya designated their month beginnings as Day 0, effectively creating a framework in which days were counted from zero to nineteen within each month.
