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.
Deuteronomy 10:12-14 NKJV
And now Israel, what does Yehovah your God (Elohim) require of you, but to fear Yehovah your God (Elohim), to walk in all His ways, and to love Him, and serve Yehovah your God (Elohim), with all your heart and with all your soul,
and to keep the commandments of Yehovah and His statutes which I (Moses)command you today for your good?
Indeed, heaven and the highest heavens belong to Yehovah your God (Elohim), also the earth and all that is in it.
