Presuppositions and Explanatory Information

1. The Hebrew Day is observed from evening to evening.

2. The AKJV of the Bible is the foundation of this calendar. The following scriptures anchor the need to involve both the sun and the moon in the computation of the dates for the celebration of the Festivals of the Bible: Genesis 1:14; Exodus 12:2; Psalm 104:19; Psalm 81:1-4. These scriptures clearly indicate the calendar must be solar/lunar.

3. The "Astronomical" New Moon (as supplied by the Naval Observatory) that is closest to the Vernal Equinox on the Hebrew Day in Jerusalem in which it falls becomes Abib 1. Passover day (Numbers 28:16 i.e. the Preparation of the Passover - Exodus 12:1-8) is on Abib 14 and the first day of Unleavened Bread will follow on Abib 15 (Numbers 33:3) which will fall very near the Full Moon, but will not necessarily be on the "Astronomical" Full Moon.

4. Pentecost Sunday is the 50th Day following seven Sabbaths (weeks), counting from the Sabbath that occurs during the festival of Unleavened Bread. To illustrate: the seven Sabbath count begins with the first Sabbath following the Festival of Unleavened Bread being counted as week one, then each subsequent Sabbath week will be counted until seven weeks are complete. This will make seven complete weeks or forty-nine days. The next day, Sunday, will be Pentecost, the fiftieth day (Leviticus 23:15-16).

5. Trumpets is the first day of the seventh month (Ethanim) of the Hebrew calendar. This is the "Astronomical" New Moon of the seventh month, and arrived at by counting the sequential new moons from Abib, the first month. The first day of Tabernacles falls very near the Full Moon of the seventh month but will not necessarily be on the "Astronomical" Full Moon.
