How Did Ancient Civilizations Measure Time ?

Ancient civilizations did not perceive time the way we do. In How Did Ancient Civilizations Measure Time ?, you will discover how the Sumerians chose base sixty to divide the day, how the Egyptians aligned their calendar with the star Sirius, and how the Maya synchronised cycles of 260, 365 and 819 days to predict planetary movements. The book explores sundials, clepsydras, incense clocks, astrolabes and the Antikythera mechanism-so many inventions that illustrate the creativity of peoples faced with the race of the stars and seasons.
Through a concise analysis inspired by the Harvard Business Review, this book highlights the influence of numerical systems (sexagesimal) and calendar reforms (Julian, Gregorian) on our daily lives. It also shows how infinitesimally small or gigantic units of time, like the Indian yugas, reflect cosmological visions. This short volume from the Collection : SAVOIR EN BREF published by Maison d'édition : Five Minutes offers a fascinating journey through the universal history of time.
It emphasises that, despite the precision of atomic clocks, we remain dependent on natural cycles. Dive into this book to understand how humans learned to domesticate time and why these ancient inventions continue to guide our calendars, rituals and modern technologies.
