The book explores the evolution of the calendar, highlighting the transition from the Julian calendar, established by Julius Caesar, to the Gregorian calendar introduced by Pope Gregory XIII. It details the inaccuracies of the Julian calendar, which underestimated the year’s length, leading to a significant discrepancy of twelve days by the late 1500s. This historical context emphasizes the necessity for a more accurate system to align civil timekeeping with astronomical events.
