Ancient civilizations, such as the Egyptians and Babylonians, observed the natural cycles of the sun and moon to determine the passage of time. They noted that the Earth takes approximately 365.25 days to complete one orbit around the sun, leading to the establishment of a calendar year. By closely monitoring the seasonal changes and celestial events, they refined their calendars to align with these observations, ultimately leading to the adoption of the 365-day year concept.
