Why is it important to know when the biblical month and new year start? Because as more people are leaving the non-biblical traditions of man that they have been taught in their churches (including the non-biblical Christian holidays) and return to the truths of the Bible (including the biblical holidays), they need to know when to celebrate YHVH’s appointed times or feasts. This means that one needs to have a basic understanding of the biblical calendar, which is different from the world’s calendar in use today. The article below (along with other articles that I’ve written on the subject which you can find at https://www.hoshanarabbah.org/teaching.html#feast) will help to explain this.

Exodus 12:2, Month. It is the Hebrew word chodesh (Strong’s H2320/TWOT 613b) meaning “the new moon, month, monthly, the first day of the month, the lunar month.” It is found in the Tanakh (Old Testament) 276 times and is translated in the King James Version as “month” 254 times, “new moon” (20 times), and “monthly” (1 time). We see that from these definitions that the terms “month” and “new moon” are synonymous. It has been understood for millennia that ancient Israelites began their month with the new moon.

Why was it important for the Israelites to know when the new moon occurred and when the month began? The dates of the annual biblical festivals that YHVH gave to Israel and instructed them to observe were determined based on when the new moon occurred (Lev 23:5, 6, 24, 27, 34).

The next question to answer is this: when does the biblical month begin? As we noted above, for modern astronomers the term “new moon” means something different than it did to the ancients, including those who YHVH inspired to write the Bible. Ancient calendars were determined by the moon, while modern ones are not. Some biblical expositors teach that the new moon begins when the moon is in conjunction or in line with the earth and the sun and is in its dark phase. Others believe that the month begins just after the moon has moved out of its dark phase and begins to show a sliver of light, which is called the visible or crescent new moon. Who is right?

Some Bible teachers claim that there is no place in the Scriptures that specifically states that the new moon begins at the first visible sliver after being dark for several days. Therefore, they reason, it is an assumption to say that it does (even though, as we will see below, this was the understanding of the ancient Israelites), and therefore, the new moon should be determined from its conjunction with the earth and sun while it is in its dark phase. While on the surface, this may seem like a valid argument, one important verse in the Scriptures, however, and some simple logic quickly disproves this notion. It is Genesis 1:14.

And Elohim 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 [moedim/biblical festivals], and for days, and years.”

In this verse we see that the sun and the moon are “signs” for seasons, days and years. The word “sign” is the ­Hebrew word owt (Strong’s H226; TWOT 41a) meaning “sign, signal, mark, token, emblem, signboard, standard.” In the Tanakh, owt describes such visible (not invisible) signs as Noah’s rainbow (Gen 9:12–13, 17), Cain’s mark (Gen 4:15), circumcision (Gen 17:11), and the Sabbath (Exod 31:13, 17; Ezek 20:12). In addition, owt is used some 80 times in the Tanakh to refer to miraculous signs. These include the plagues of Egypt (Exod 7:3; Deut 4:34, etc.), the sign of the virgin birth of the Messiah (Isa 7:11, 14); YHVH miraculous signs to Gideon (Judg 6:17) and King Hezekiah (2 Kgs 20:9; Isa 38:7). In addition, Aaron’s rod that budded was a sign or token (Num 17:25). Many more examples could be given.
