Who Made The First Calendar

Humans have always had a fascination with time and its measurement. The earliest civilizations used various methods to keep track of days, months, and years. But who made the first calendar?

The First Calendar

The Egyptians used the calendar to keep track of the flooding of the Nile River, which was crucial for agriculture. They also used it to keep track of religious festivals and ceremonies.

Other Early Calendars

Other early civilizations also created calendars. The Sumerians, who lived in Mesopotamia around 4000 BCE, used a lunar calendar that was based on the cycles of the moon. The calendar had 12 months of 29 or 30 days each, with an extra month added every few years to keep it in sync with the solar year.

The ancient Greeks used a calendar that was based on the cycles of the moon and the sun. The calendar had 12 months, alternating between 29 and 30 days, with an extra month added every few years.
