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 12:4-6 NKJV
And in that day, you will say:
Praise Yehovah, call upon His Name; Declare His deeds among the peoples, make mention that His Name is exalted.
Sing to Yehovah, for He has done excellent things; This is known in all the earth.
Cry out and shout, O inhabitants of Zion, for great is the Holy One of Israel in your midst (center)!
