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.
Romans 8:22,23 NKJV
For we know that the whole creation groans and labors with birth pangs together till now,
Not only that, but we also who have the firstfruits of the Spirit, even we ourselves groan within ourselves, eagerly waiting for the adoption (sonship), the redemption (resurrection) of our body.
