Feasts & New Moon Dates

Following are dates of the Biblically commanded Feasts for the coming year.  These are not only Jewish Holy Days.  In Leviticus 23:2 YHVH tells us, “These are My appointed festivals, the appointed festivals of the Lord, which you are to proclaim as sacred assemblies.”  They are YHVH’s specially appointed times available to all His followers.  Mark your calendar and plan ahead to participate with YHVH on His Holy Days!

Understanding the Conjunction New Moon and Rosh Chodesh…

The moon begins to illuminate immediately after conjunction. We cannot see it, though, until the sun sets because the moon is obscured by the greater light of the sun. The fact that we cannot see the moon immediately after conjunction, however, does not negate the fact that it has already began a new revolution with new illumination. Often, the first visible crescent can only be seen a day or two later, either on the following evening of New Moon Day which then call day 1 , or even seen a day later, and this is why we don’t wait to see the crescent moon to call day 1, but simply use the crescent as a confirmation of the new month.

Enoch and Philo record the ancient way of the Moon:

We should all have the unwavering desire to serve and please the Eternal One and keep his commandments, (Ecclesiastes 12:13) for this is the duty of Man. The Book of Enoch is a biblical reference and also serves as a historical reference when mentioning the Luminaries.  Enoch mentions in full detail the elements and behaviors of the Lunar Cycle and how to determine when the Moon is: ‘NEW, FULL and in CONJUNCTION’ by human observation.  The book of Enoch at one time was part of Scriptural writings and in Enoch 73:4 it says that the moon rises in this manner: Its head faces the easterly direction, coming out on the thirtieth day, on that day, that is, on the thirtieth day, it comes into existence, and it appears with the sun in the gate through which the sun exits; and you have the beginning of the month.  

And on the first day she is called the NEW MOON, for on that day the light rises on her. (Enoch 78:12) 

Philo (a Hellenistic Jewish Philosopher from Alexandria) lived before, during, and after Yeshua (20BCE-50CE), and it stands to reason, that he would have also espoused a correct understanding of Biblical calender and how to observe the cycle of the moon determining the months.  Philo confirms what Enoch wrote in ancient times saying that the New Moon festival takes place when the moon begins to illuminate. As previously stated, the moon becomes illuminated immediately after conjunction. We cannot see it, though, until the sun sets because the moon is obscured by the greater light of the sun. The fact that we cannot see the moon immediately after conjunction, however, does not negate the fact that it has already began a new revolution and is again re-illuminating. Often, the first visible thin almost imperceivable crescent will be seen on the evening of New Moon Day, displaying to the viewer her new light.

“Following the order which we have adopted, we proceed to speak of the third festival, that of the new moon. First of all, because it is the beginning of the month, and the beginning, whether of number or of time, is honorable. Secondly, because at this time there is nothing in the whole of heaven destitute of light. Thirdly, because at that period the more powerful and important body gives a portion of necessary assistance to the less important and weaker body; for, at the time of the new moon, the sun begins to illuminate the moon with a light which is visible to the outward senses, and then she displays her own beauty to the beholders…” (Philo, Special Laws II, Section XXVI (140-142), emphasis supplied)

In the following quotations, Philo plainly states that New Moon Day follows conjunction and that months are reckoned from conjunction to conjunction.

“The third [festival of Yom Teruah] is that which comes after the conjunction, which happens on the day of the new moon in each month.” (Philo, Special Laws II, Section XI (41))

“This is the New Moon, or beginning of the lunar month, namely the period between one conjunction and the next, the length of which has been accurately calculated in the astronomical schools.” (Philo, Special Laws II, Section XXVI (140))

Philo’s statements below indicate that the moon completes its perfect configurations (i.e. waxing half-moon, full moon, waning half-moon, conjunction) at the end of each week. When reckoning the dawn after conjunction as the commencement of New Moon Day, this is most often the case.

Full Moons always at the end of the 14th day and beginning of the 15th:

Enoch and Philo also state that the moon should be full at the end of the second week (i.e. the 15th day of the lunar month).  Enoch 78:6 tells us,

and on the fourteenth day the moons light becomes

Note: When reckoning the day after conjunction as New Moon Day, the moon will full on the evening after the 14th leading into the 15th of the month.

And the next verse 7 confirms:

 “…On the fifteenth day her light is full…”

Thus the moon is fifteen days old by the time her light is full. 

“For it is said in the Scripture: On the tenth day of this month let each of them take a sheep according to his house; in order that from the tenth, there may be consecrated to the tenth, that is to [Elohim], the sacrifices which have been preserved in the soul, which is illuminated in two portions out of the three, until it is entirely changed in every part, and becomes a heavenly brilliancy like a full moon, at the height of its increase at the end of the second week . . .” (On Mating with the Preliminary Studies, Section XIX, (106))

“And this feast is begun on the fifteenth day of the month, in the middle of the month, on the day on which the moon is full of light, in consequence on the providence of Elohim taking care that there shall be no darkness on that day.” (Philo, Special Laws II, The Fifth Festival, Section XXVIII (155))
