When Does A Month Begin?

And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: Gen. 1:14 (The word “seasons” is from Strong’s#4150, mow’ed, meaning “appointed time,” “meeting,” or “set feast.” This is the same word used in Lev. 23:2 to describe God’s appointed feasts which were “sacred assemblies.” These “sacred assemblies” were the Sabbath day, along with the annual holy days. The moon was appointed to tell us the time of God’s assemblies.)

He appointed the moon for seasons
: the sun knoweth his going down. Psalm 104:19(Again the word seasons comes from “mow’ed.” So the moon was appointed to tell us what day God’s sacred assemblies were.)

And in the beginnings of your months ye shall offer a burnt offering unto the LORD;… this is the burnt offering of every month throughout the months of the year. Num. 28:11,14 (This day of observance is the new moon day, every month on the 1st day of each month.)

For as the new heavens and the new earth, which I will make, shall remain before me, saith the LORD, so shall your seed and your name remain. And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the LORD. Isaiah 66:22-23 (In the future at the new heavens and new earth, the new moon days and Sabbath days will be worship days for the people of God. New moon days and Sabbath days were observed in the Bible days. And they are to be observed today as well, even though few people do this.)

Also in the day of your gladness, and in your solemn days, and in the beginnings of your months, ye shall blow with the trumpets over your burnt offerings, and over the sacrifices of your peace offerings; that they may be to you for a memorial before your God: I am the LORD your God. Num. 10:10 (Trumpets were to be blown on new moon day. The Feast of Trumpets is the 1st day of the 7th month and is symbolic of the return of Christ. Thus the new moons are symbolic of and parallel the 7 trumpets of the 7th seal of Revelations. The trumpets are warning blasts to remind us to repent of our sins now before the return of Christ so that we may be spared punishment of his wrath.)

Blow up the trumpet in the new moon, in the time appointed, on our solemn feast day. For this was a statute for Israel, and a law of the God of Jacob. Psalm 81:3-4 (This is the key verse that supports the conjunction to be the new moon. Reference all the different translations. Half say “appointed” and the other half say “full moon.” The words “new moon” comes from Strong’s#2320, Chodesh, or root#2318 meaning “to be new,” “renew,” or “repair.” The word “appointed” comes from Strong’s#3677, kece’, meaning “full moon,” or root#3680 meaning “concealed” or “covered.” Proverbs 7:20 also uses this same word kece’ and is translated “full moon.” So the new moon is the full moon that is covered, concealed, dark, or hidden. Also the trumpet was blown on the new moon, which is a solemn feast day.)

Shall not the day of the LORD be darkness, and not light? even very dark, and no brightness in it? Amos 5:20 (The trumpet blasts of the new moon days were warning sounds that the Day of the Lord was coming. The 7th new moon is the Feast of Trumpets, which represents the 7th trumpet of Revelation, which is the return of the Messiah. The description of this day appears to support the conjunction moon as being the new moon and not the crescent.) 

Then the Lord my God will come, and all the holy ones with him. On that day there will be no light, no cold or frost. Zech. 14:5-6 (No light on that day, the same day of the 7th new moon day of the year, which is the Feast of Trumpets. Therefore the new moon is the conjunction, not the crescent.) 

That day is a day of wrath, a day of trouble and distress, a day of wasteness and desolation, a day of darkness and gloominess, a day of clouds and thick darkness, A day of the trumpet and alarm against the fenced cities, and against the high towers. Zeph. 1:15-16 (The day of the trumpet is a day of darkness. Just another clue that suggests a dark new moon.)

And David said unto Jonathan, Behold, to morrow is the new moon, and I should not fail to sit with the king at meat: but let me go, that I may hide myself in the field unto the third day at even. 1 Sam. 20:5 (David observed the new moon.)
So David hid himself in the field: and when the new moon was come,… And it came to pass on the morrow, which was the second day of the month, 1 Sam. 20:24,27 (The day after the new moon is considered the 2nd day of the month, and thus the new moon day being the 1st day of every month.)

And he said, Wherefore wilt thou go to him to day? it is neither new moon, nor sabbath. 2 Kings 4:23 (The woman whose son had died told her husband that she was going to the man of God. And the husband questions why since it was neither a Sabbath or a new moon day. Sabbath and new moon days are days of worship.)

New Moon Day Is Day "OF" Conjunction, NOT Day After

Now to clarify, the 1st day of the month is not the day after conjunction as many teach. It is the very day the conjunction occurs in. None of the days after conjunction fits the Hebrew definition of new moon. There is ONLY ONE DAY each month that is unique enough to fit ALL the qualification of the Hebrew definition of new moon, and that is the day it becomes new IN! Remember the definition of new moon is “new month”, taken from the Hebrew word which means, “to be new”, “to rebuild”, “to renew”. The new moon cycle does not become new in any of the days following conjunction day, and therefore they do not fit all the Hebrew definition of new moon and therefore none of them can be the scriptural day of the new moon. It’s that simple. Although all of the days after conjunction possibly fits PART of the definition, namely, the “rebuild” part, but NOT the “new month” part, or the “to be new” part, or the “renew” part, because the moon is hours old by the time the next day’s begins. The new moon cycle does not “become new” in any of the days after conjunction day, nor does it “renew” in any of them. 

When a new baby is born, that whole day is the day of its birth, no matter what time of the day the new baby is born, it is its birthday. Now the day after the day that the new baby is born in, is the first full 24-hour day of the new baby’s life, BUT it is not the day of its birth, or the day in which the new baby became new! The same is true with the birth of a new moon, after the old moon has died out at conjunction. The new moon cycle becomes new on the day of conjunction, and the next day is the first full 24 hours of the new moon’s rebuilding, BUT it is not the day in which the moon actually became new, and therefore it is not the day of the new moon!

The Scripture in Ezekiel 46:1 says for us to worship “in” “the day of” the new moon”. The Phrase “in the day of” is 284 times in Scripture and always refers to the day in which something happens [not the day after], and is always the first day of the happening, and no matter what time of day it happened, it is counted as a whole day. If we were told to worship in the day of the full moon, would we then honor the day after or the day in which the moon actually became full? Common sense says we would honor the day the moon became full. The same is true when we are instructed to honor the day in which the moon becomes new, which is at conjunction. 
This mindset is also confirmed in Philo’s writings, where he describes the conjunction and says that “the law honors the end of the moon’s orbit/cycle, at the point that it began to travel, by having called THAT DAY a feast,” [obviously THAT DAY is referring to the whole day of the conjunction even though the conjunction can happen in part of the day.] THE SPECIAL LAWS,11 verse 142 page 581
Notice Philo is saying that the law honors that day [or conjunction day] by calling it [the whole day] a feast! Philo lived during the time of our Savior and worshiped on the same new moon day. Philo is not saying that the law honors the HOUR of the conjunction, or new cycle, but the DAY of it, or the whole day in which it happens!
