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.
Matthew 6:34 NKJV
Therefore, do not worry about tomorrow, for tomorrow will worry about its own things. Sufficient for the day is its own trouble.
