Biblical Understanding based on the Record of Scripture
YHVH created the sun and the moon and set them in the heavens, in part, to show when to observe His Festivals. The date listed on this calendar for the start of the 1st month and the 7th month is based on the first projected sighting, after sunset, of the renewing of the light of the moon.
Isaiah 12:1-3 NKJV
And in that day (Israel and Judah) you will say:
O Yehovah, I will praise You; Though You were angry with me, your anger is turned away, and You will comfort me.
Behold, God is my salvation, I will trust and not be afraid; for YAH, Yehovah is my strength and song; He also has become my salvation.
Therefore, with joy you will draw water from the wells of salvation.
