Calendar System Shifts oleh Felicia Dunbar

Calendar System Shifts explores the fascinating history of calendar systems, revealing how these methods of timekeeping are not simply neutral tools but are deeply intertwined with cultural, religious, and political power structures. Examining systems such as the Egyptian, Mayan, Julian, and Gregorian calendars, the book highlights how astronomical observations formed the basis for early calendars, influencing everything from agricultural practices to religious observances. Discover how calendar reforms often represent deliberate attempts to consolidate power or redefine social norms, challenging the authority of our current timekeeping methods. The book delves into the societal and political ramifications of calendar reforms, emphasizing that these shifts are rarely purely technical adjustments. By providing essential background on astronomy and the history of mathematics, Calendar System Shifts illustrates how calendars, while rooted in the natural world, are human constructs designed to serve specific purposes.

The book progresses by introducing fundamental astronomical concepts, analyzing major calendar systems and their reforms, and culminating in a discussion of standardized global time and the challenges of reconciling cultural and scientific approaches to timekeeping. Through archaeological findings, historical documents, and astronomical records, the book offers a unique perspective by viewing calendar reforms as strategic decisions with profound social and political consequences. This interdisciplinary analysis connects to astronomy, anthropology, and political science, making it valuable for students, scholars, and anyone interested in the origins and implications of our modern timekeeping systems.
