This caused the year to have only 354 days. Thus after several years, in order to keep the seasons correct, they would have to add a thirteenth month.
During this year with 13 months the sowing and reaping months did not align properly with the seasons and crops would suffer. This is the origin of “unlucky thirteen”.
They did this by looking at the twelve constellations through which the Sun passes in a year.
These constellations together are called the zodiac.
Starting about 600 B.C., the Greeks were the first to try to describe the cosmos (the orderly arrangement of the universe).
Their concepts were based on religion or philosophy, not science.
The Earth was thought to be a flat disk floating in water, air or space.
