The 7th Day is Hesed = At its completion is equivalent to age 20, but begins at age 19.

            The 1st Day is Malkuth, age 13.  That is the age of accountability where Mankind became responsible for all error and sins.

Mankind develops (as a whole), one Day at a time.

            The 8th Day corresponds to Binah, the lowest of the True Heavens.  This is the Day of Convocation which followed Sukkoth (Feast of Tabernacles).  Spiritually, this marks the end of Blessed souls dwelling in fleshly bodies.  Israel, the True Christ rejoices undisturbed with YHVH undisturbed by souls of wickedness.
