Iranian Solar Calendar and Endurance of Nowruz in Persian Time Culture

This book is a study of the profound relationship between the Iranian solar calendar, collective memory, and the historical identity of Iranians. The author seeks to demonstrate how the solar timekeeping system has not only endured through the turbulent course of Iranian history but has also become a foundational component of the cultural, political, and historical identity of the inhabitants of Iran. By tracing the historical roots of the solar calendar-particularly the formulation of the Jalali calendar in the medieval period and its formal adoption during the Pahlavi era-the author explores why celebrations like Nowruz have remained alive in the national memory of Iranians, while other ancient festivals such as Mehregan have faded into obscurity. At the heart of this inquiry is the role of collective memory-as the shared reservoir of a nation's historical experiences, knowledge, and recollections-in sustaining and regenerating Iranian identity. With a critical approach to concepts like "historical memory" and "national identity," the author analyzes how calendrical and temporal markers serve as vital elements in shaping a nation's cultural and historical cohesion. This book is the first systematic study to examine the Iranian solar calendar through the lens of collective memory and identity formation. It offers a significant contribution to Iranian studies and cultural history by addressing a long-standing gap in the literature.
