When a person travels from one place to another, he looks to the right to see nature and the mountains, so he knows where he is and he looks to the left and sees the median strips so that he is safe in the right direction , and if we imagine that we are in the dark universe. We will not know whether we are moving or not, nor will we be able to see whether we are approaching or moving away from our goal, and in a short time we will lose our bearings and become desperate.
Likewise, calculating the number of years means that we have to define our life path. The sun and moon represent both sides of the road, and both are the opposite of darkness, but with different roles, the sun is bright and represents the right side to know where we are, and the moon is the light that is left side represents the white line to know the right side of the street. If a nation takes the moon alone to calculate the number of years, it is like the one who only looks at the white line, it will not know where it is, and the one who depends on the solar calculation is also like the one who looks to the right. He’ll know where he is, but he won’t know which side of the street he’s on, the result is disaster. The sun and the moon must therefore be recognized and taken into account by calculating the number of years
