The Reason for the Calendar

The calendar is a series of numbers divided into days, weeks, months, and years. Its purpose is to establish dates and measure equal time intervals. It was invented around the year 4236 B.C. by the Aztecs. The calendar used today is very different, yet similar. The calendar used today is based on divisions of rotations of the earth, sun, and moon. The moon rotates around the earth, and the earth around the sun, causing a revolution.

The earth rotating an its axis one full time is called a day. The earth revolving around the sun is called a year. The in between times of getting different angles of light are called months and hours. The hours are caused by the sun being at different angles of the left, above, and right when facing north. For instance, when the sun rises it is to the east, and when it falls, it is to the west. You may also find on a sunny day the sun is straight above at noon.

The word calendar accuatly means a systematic arrangement of subdivisions of times, as years, months, days, weeks, etc; almanac. It comes from the Latin word calendaeium, meaning account book or calendae, meaning calends, ( First day of Roman calendar).
