Recognizing and calculating the dates from the moon.
At
least thirty thousand years ago humans living in the cave learned to recognize
the dates from the changing patterns of the moon. The images found
in these caves have evidence of this type of calendar.
The current international calendar came into being from the moon
calendar.
The
current name of the international calendar is the Common Era
calendar. Until a few years ago it was called the Gregorian calendar, because
it was made by omitting the error of the coming ten days in the Julian calendar
on the orders of Pope Gregory in 1582 A.D. While the Julian calendar was made
by the Roman Emperor Julius Caser by making some adjustments to the Roman
calendar. At that time, a priest was appointed to observe the sky. The day when
he saw the new crescent moon for the first time on the western horizon after
sunset, he would call out to the people and announce the beginning of next
month. For centuries the Romans used the word Calando or Calends for the first
day of the month. They extracted the word at the weight of the Italian word
Claire. They drew the word on the weight of the Italian word Claire, whose meaning
was the final announcement. As a result of this ritual the word calendar came
into being which means to post in advance the dates of the coming year, sorted
by week and month names so that, people
can use these dates for their social, economic, cultural and religious
activities, depending on current or upcoming seasons.
