Chronology of calendar: Human evolution journey

Abstract

Numerology is a divine science that helps in knowing about the future of a person. The assessment of numerology is based on the date of birth which is in turn based on calendars. Astronomy plays a vital role in many early civilizations, and one of its most important applications is timekeeping. Over centuries of human history, many calendars have been used worldwide to order time systematically. An essential part of timekeeping is calendars, as these are essential in religious practice, agriculture, and governance. To produce a calendar, it is necessary to determine the length of a solar year and a lunar month, known as a lunisolar calendar. In earlier times, calendars were produced by observing the different phases of the moon and sun and their relationship with fixed constellations in the sky. Also, equinoxes and solstices were considered. Today, the Western Gregorian calendar is a global standard for business and diplomatic purposes. People of various religions, nations, and societies still employ ancient calendars to mark the days of religious importance. Knowing the history of calendars helps visualize the progression of events within a given historical narrative. In other words, it helps figure out which calendar came first and what impact it had on the people who followed it. It can also be linked with current practices in numerology and astrology.
