The new moon is the full moon.  The moon was made on the fourth day of creation. The moon rules the night and is for signs and seasons.

and let them be for signs, and for seasons, and for days, and years:”

verse 17: “And God set them in the firmament of the heaven to give light upon the earth,”

verse 18: “And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.”
