However, since Earth rotates from West to East, all the other heavenly objects appear to be moving in the opposite direction, i.e., from East to West since the pole star also appears to be fixated in one place, it seems like the other stars revolve around it. It is one of the brightest star in the sky and can be seen almost every night. However, it cannot be seen from some points in the Southern hemisphere.

Solution

The time taken for one revolution of moon is a few hours longer than 29 days. But for ease of calculation, these hours have been divided amongst the months to give us months having 30 and 31 days. It takes one complete revolution of the moon around the Earth to have the next new moon day after the previous one. This period is called a month.
