The Menorah

The biblical Menorah has "seven" lamps.  As there are SEVEN biblical feasts which relate to the PHASES of the moon.  The time of the "Sabbath" can be found by knowing ASTRONOMY as well.

Qumran Calendar moon phases are as follow: 1st of Abib: Full Moon(cycle 1), Passover: New Moon (cycle 1), Feast of Weeks/Pentecost: Full Moon (cycle 3), Atonement: New Moon (cycle 1) or Trumpets: New Moon (cycle 2), Tabernacles: Full Moon (cycle 2), End of Tabernacles: (cycle 2) 1/2 moon

Or another way of looking at it:

-Abib 1: Full Moon (New Year)

Abib 14: New Moon (Passover)

-Sivan 1: Full Moon (Fest of Weeks)

-Sivan 14: New Moon (Feast of Weeks)

-Tishri 1: Full Moon (Trumpets)

-Tishri 10: New Moon (Atonement)

-Tishri 23: 1/2 Moon (End of Tabernacles)

It would depend upon what Calendar Cycle a person uses, but each "lamp" would represent a phase of the moon which would point to the time for biblical feast.

Or the FEAST of DEDICATION can be a sign too!  Yes, Chislev 24: Full Moon (Feast of Dedication, Cycle 1), Tebeth 1: 1/2 Moon (End of Feast of Dedication, Cycle 1)....

What is an easy way to "convert" the biblical menorah from Qumran Calendar to Modern-Day Gregorian Calendar?

Look for the equinox and solstice!  First two signs in Abib (Immediately after the Spring Equinox).  Second two signs in Sivan (Immediately before the Summer Solstice), Last three signs in Tishri (Immediately after the Fall Equinox).  The addition of JESUS celebrating the "FEAST OF DEDICATION" can be found by looking for the sign in the month of CHISLEV/TEBETH (immediately before and after the Winter Solstice)
