Aviv Barley in the Biblical Calendar

6-Row-BarleyBiblical Leap Years

The Biblical year begins with the first New Moon after the barley in Israel reaches the stage in its ripeness called Aviv. The period between one year and the next is either 12 or 13 lunar months. Because of this, it is important to check the state of the Barley crops at the end of the 12th month. If the barley is Aviv at this time, then the following New Moon is Hodesh Ha-Aviv ("New Moon of the Aviv"). If the barley is still immature, we must wait another month and then check the barley again at the end of the 13th month.

By convention, a 12-month year is referred to as a Regular Year while a 13th month year is referred to as a Leap Year. This should not be confused with Leap Years in the Gregorian (Christian) Calendar, which involve the "intercalation" (addition) of a single day (Feb. 29). In contrast, the Biblical Leap Year involves the intercalation of an entire lunar month ("Thirteenth Month", also called "Adar Bet"). In general, it can only be determined whether a year is a Leap Year a few days before the end of the 12th Month.

Where is Aviv Mentioned in the Hebrew Bible?

The story of the Exodus relates "This day you are going out in the the month of the Aviv." (Ex 13:4).

To commemorate that we left Egypt in the month of the Aviv, we are instructed to bring the Passover sacrifice and celebrate the Feast of Unleavened Bread (Chag HaMatzot) at this time of year. In Dt 16:1 we are commanded:

"Keep the month of the Aviv and make the Passover (sacrifice) to Yehovah your God at night, because in the month of the Aviv, Yehovah your God took you out of Egypt".

Similarly, we are commanded in Ex 23:15,

"You will keep the Feast of Unleavened Bread; seven days you will eat unleavened bread, as I have commanded you, at the time of the month of the Aviv, because in it you went out of Egypt."

The same is commanded in Ex 34:18,

"You will keep the Feast of Unleavened Bread; seven days you will eat unleavened bread, as have I commanded you, at the time of the month of the Aviv, because in the month of the Aviv you went out of Egypt."

What is Aviv?

Aviv indicates a stage in the development of the barley crops. This is clear from Ex 9:31-32 which describes the devastation caused by the plague of hail:

"And the flax and the barley were smitten, because the barley was Aviv and the flax was Giv'ol. And the wheat and the spelt were not smitten because they were dark (Afilot)."

The above passage relates that the barley crops were destroyed by the hail while the wheat and spelt were not damaged. To understand the reason for this we must look at how grain develops. When grains are early in their development they are flexible and have a dark green color. As they become ripe they take on a light yellowish hue and become more brittle. The reason that the barley was destroyed and the wheat was not is that the barley had reached the stage in its development called Aviv and as a result had become brittle enough to be damaged by the hail. In contrast, the wheat and spelt were still early enough in their development, at a stage when they were flexible and not susceptible to being damaged by hail. The description of the wheat and spelt as "dark" (Afilot) indicates that they were still in the stage when they were deep green and had not yet begun to lighten into the light yellowish hue which characterizes ripe grains. In contrast, the barley had reached the stage of Aviv at which time it was no longer "dark" and at this point it probably had begun to develop golden streaks.

Parched Aviv

We know from several passages that barley which is in the state of Aviv has not completely ripened, but has ripened enough so that its seeds can be eaten parched in fire. Parched barley was a commonly eaten food in ancient Israel and is mentioned in numerous passages in the Hebrew Bible as either "Aviv parched (Kalui) in fire" (Lev 2,14) or in the abbreviated form "parched (Kalui/ Kali)" (Lev 23:14; Jos 5:11; 1Sam 17:17; 1 Samuel 25:18; 2 Samuel 17:28; Ruth 2:14).

While still early in its development, barley has not yet produced large enough and firm enough seeds to produce food through parching. This early in its development, when the "head" has just come out of the shaft, the seeds are not substantial enough to produce any food. At a later stage, the seeds have grown in size and have filled with liquid. At this point the seeds will shrivel up when parched and will only produce empty skins. Over time the liquid is replaced with dry material and when enough dry material has amassed the seeds will be able to yield "barley parched in fire".

Aviv and the Harvest

The month of the Aviv is the month which commences after the barley has reached the stage of Aviv. 2-3 weeks after the beginning of the month the barley has moved beyond the stage of Aviv and is ready to be brought as the "wave-sheaf offering" (Hanafat HaOmer). The "wave-sheaf offering" is a sacrifice brought from the first stalks cut in the harvest and is brought on the Sunday which falls out during Passover (Chag HaMatzot). This is described in Lev 23:10-11,

"When you come to the land which I give you, and harvest its harvest, you will bring the sheaf of the beginning of your harvest to the priest. And he will wave the sheaf before Yehovah so you will be accepted; on the morrow after the Sabbath the priest will wave it."

From this it is clear that the barley, which was Aviv at the beginning of the month, has become harvest-ready 15-21 days later (i.e by the Sunday during Passover). Therefore, the month of the Aviv can not begin unless the barley has reached a stage where it will be harvest-ready 2-3 weeks later.

That the barley must be harvest-ready 2-3 weeks into the month of the Aviv is also clear from Dt 16:9 which states:

"From when the sickle commences on the standing grain you will begin to count seven weeks."

From Lev 23:15 we know that the seven weeks between Passover (Chag Hamatzot) and Pentecost (Shavuot) begin on the day when the wave-sheaf offering is brought (i.e. the Sunday which falls out during Passover):

"And you shall count from the morrow after the Sabbath, from the day you bring the sheaf of waving; they will be seven complete Sabbaths."

Therefore, the "sickle commences on the standing grain" on the Sunday during Passover, i.e. 2-3 weeks after the beginning of the month of the Aviv. If the barley is not developed enough so that it will be ready for the sickle 2-3 weeks later, then the month of the Aviv can not begin and we must wait till the following month.

It should be noted that not all the barley ripens in the Land of Israel at the same time. The wave-sheaf offering is a national sacrifice brought from the first fields to become harvest-ready. However, the first-fruit offerings brought by individual farmers can vary in ripeness anywhere from "Aviv parched in fire" to fully ripe grain which may be brought "crushed" or "coarsely ground". This is what is meant in Lev 2:14,

"And when you bring a first-fruit offering to Yehovah; you shall bring your first-fruit offering as Aviv parched in fire or crushed Carmel" (Carmel is grain which has hardened beyond Aviv to the point where it can be "crushed" or "coarsely ground").

All of the above passages have been translated directly from the Hebrew and it is worth noting that the King James translators seem to have only understood the various Hebrew agricultural terms very poorly. In Lev 2:14 they translated Carmel as "full ears" and "Aviv" as "green ears" whereas in Lev 23:14 they translated Carmel as "green ears"!

In summation, barley which is in the state of Aviv has 3 characteristics:

  1. It is brittle enough to be destroyed by hail and has begun to lighten in color (it is not "dark").
  2. The seeds have produced enough dry material so it can be eaten parched.
  3. It has developed enough so that it will be harvest-ready 2-3 weeks later.

    Is there a way to start the tri-Anual torah portions on the real new year Aviv? Please help me with this. May Yehovah continue to bless you and love one’s. Torah.

  • David Matherly says:

    The Prophecy in Daniel concerning the changing of the times seasons and the law obviously have already occurred since about 80 AD when it was decided to no longer wait for the Priests in Jerusalem to establish Abib, the Passover could be observed a month later but never before. Furthermore why is there so much concern as to alignment to the solar calendar? The children of Israel were to be a holy and peculiar people and were to obey the Word and Law of the LORD GOD, and they were told not to be like the other nations nor to observe their times or observances. My prayer for the true Children of Israel is that they will come together and declare a national convocation where they will read the Law and reconfirm the Covenant just as they did in the days of Nehemiah and Ezra.

  • Aldo says:

    Hello Nehemia,
    This year 2021, Passover is supposed to occur on March 27. This year the month of Abib (nissan) will occur before the Vernal Equinox which will occur on March 20. I this kosher for Abib to begin before the Vernal Equinox? Do you still have spotters for the ripened Barley which would resolve the issue as to whether March 27 is the correct date for the Passover?
    Thanks in advance for your response,
    P.s. Have watched your presentation “The Hebrew Yeshua vs The Greek Jesus” many times – excellent presentation. Kudos.

    • Jessica says:

      Hi Aldo, thank you for your question. I am on the same search. I am doing some digging, but I was wondering if you’d be willing to share what you find in this thread? And if I find anything, I’ll do the same 🙂

    • Richard Gutknecht says:

      I’m actually looking into a calendar based upon the first new moon following the spring equinox. The barely this year was in all different stages of development and there was much confusion over the beginning of the year. The scriptures state the month must have aviv barley, but does not state the barley determines the begining of the month. But following the lights in heaven that are given for determining the appointed times. (Genisis 1:14) If we follow this model, the barley will always be in an aviv state, and the subjective evaluation by men is eliminated. This would provide order instead of confusion.

  • John Humphrey says:

    I don’t know much about Karaite Judaism, but I only view the TaNaK as authoritative. I believe that only by obeying YHWH’s directions can salvation be had. I believe that YHWH is my one and only savior. I believe that sin (not obeying YHWH’s law) is forgiven by obeying His laws. I am currently working on a Excel file to codify all of YHWH’s directions, then I will build study tools, I will memorize all YHWH’s laws, live them and teach them. Do Karaites do this as well? I read somewhere that the only Karaite temple is in Los Angeles, and I haven’t been able to get them to return my calls or emails. Can you guys help me?

    • Amanda says:

      The scriptures clearly say that sin IS breaking the law, and that sin can be covered by LOVE.

    • Andre Jacobs says:

      Hi there, I am not folliwing this blog, I was busy reading on the barley feasts. But your comment on sin and how to overcome it drew my attention! I do not know your beliefs..but if you are a Christian..you should know that the only forgiveness for sin and way back to the Father is by and through Jesus Christ! Be blessed.

  • Andrea Acker says:

    Nehemia, Devorah – Why not given all your work study and input on this matter, make an online and printable calendar for those of us trying to keep a literal biblical calendar. Obviously the print calendar would have to wait until the AVIV state had been determined to be printed and would have to thus be done each year, but I for one would buy several, and an online calendar could be updated instantly!

    • Kristian Marius Simon says:

      Hi Andrea, did you received any answer about calendar. I am also traying to get it, but I can’t find any info where or how.Greetings

  • James M Greer says:

    Prior to the Exodus, what was the first month?

    • Nicole Carlson says:

      It was the same from the beginning, Israel had just lost their way in the counting. Refer back to Yeshua telling Abraham & Sarah that Isaac would be born the following year at the “appointed time” which is translated Moed. So we know it was a Feast Day, having been established before the Exodus. Looking all the way back to Cain and Abel one can ask, “Why was sacrificing his harvest from the ground so terrible? Aren’t we to also bring an offering of our means before the Lord?” To answer that one would have to refer back to the fact that sin caused the first sacrifice of an animal to ‘cover’ Adam and Eve’s nakedness. That Sacrifice was held to be the first sign that God would one day provide the ultimate sacrifice. I believe this was on Passover because it fits that God also was angry with Cain because he would not acknowledge the “Lamb that taketh away the sin of the world” but instead wanted to offer his own idea of a sacrifice, thus nullifying the plan of salvation that God had put forth. That was the REBELLION that rose up against his brother, Abel, and Cain’s spirit of evil is what rose up and killed his brother. I believe this also was on Passover. Down through the ages, God has adhered to his plan of salvation and to his Calendar.

      One more point, we also know that the manna was given and then withheld on the Sabbath Day, so we know God’s Covenant was already in place before he gave it on Mt. Siani – which was after the manna had been given.

      • bman says:

        The Sabbath Day was a commemoration of Creation and was (likely) in effect from Creation onward. It was incorporated into the First (Old) Covenant which was given on Mt. Sinai. Prior to Sinai there were other covenants (eg with Adam, Noah, Abraham) but not with the Hebrew people as a nation – there was no Hebrew nation to covenant with. God’s Old Covenant was given at Mt. Sinai and was an extension of, and incorporated much of what had been covenanted previously. The New Covenant was ratified by Jesus and, as Paul makes very clear, it replaces / ENDS the Old Covenant for all those who will accept it. If we do not accept the New Covenant, by default we are under the Old Covenant with all it’s laws which are impossible for us to keep to God’s standard of perfection; and we are lost.

  • Lisa G Sims says:

    When was the beginning of the month of the month of Aviv this year?

  • Delle Kistler says:

    I find your articles very helpful. Thank you for your dedicated work. In looking through the comments, I haven’t found guidance regarding how much of a field needs to be in Aviv, before the time of Aviv is declared. Is there a rule of thumb? Half a field? More? Less?
    Thank you.

  • qfc7 says:

    As in previous years, I sense there is a hesitancy to jump the gun and announce the maturity of the barley harvest. Father’s observational calendar is such that it requires a moderate degree of faith on our part whereby we wait to hear of when Father chooses to begin His sacred calendar year. I guess part of the reason so many in our Faith Community favor the calculated Jewish Calendar is that we know well in advance what time it is (although the Jewish Calendar places the head of the year at the 7th Month–sigh). But this excited anticipation over the maturity of the barley is one of the things I look so forward to each year. It challenges me to trust Father and to orient my thoughts and plans toward Him and Him alone. Shalom.

  • Michael Asare says:

    Please l live in Ghana (West African) and will be very happy to know if the barley is Aviv. Thank you, Yeshua bless you.

  • Robert M Martin says:

    I am also looking for the ripening of the winter Barley! Those of us of like minds surely thank you for your efforts to bring forth is most important time of the year. Will the day be given when the 1st observance is noted?

  • Donna Chavez says:

    Please keep me informed when the Barley is ripe this Gregorian calendar year 2018. I keep seeing people post when the Passover will be, two different times, but how can they know for sure when they know not when the Barley is ripe? Thank you very much!

  • Elena says:

    If our Father created the world in 6 days and rested on the 7th day and in Exodus 12:16 says; And in the 1st day there shall be an holy convocation, and in the 7th day there shall be an holy convocation to you; no manner of works all be done in THEM, save that which every man must eat, that only may be done of you. How exactly do I count the 1st day in the 7day week?

  • Elena says:

    Ezekiel 1: 1 says 13th year, in the 4th month. In the 15th day of the month. It does not say 13th month

  • George T says:

    You have said (on your dvd) Aviv is only Aviv in Israel, not any other part of the world. However, in this article your refer to Ex. 13:4 and Dt. 16:1, neither of which, places the Jewish people in Israel. In fact, at this point in history, they are referred to as Hebrews.
    Can you explain this “discrepancy”?

    • Yochanan says:

      Hebrew means “Crossed Over”. Given to Father Abraham. The english word “Jew” is really what the Romans called the people of the “Southern Tribes” of Yahuda, Benhamyn, and Levi and are to this day but is often used to describe The Israelites but that would miss the mark as they are subset of the 12 tribes. The Northern Tribes of Israel are made up of 10 Tribes and were dispersed hundreds of years BC and make up many of the people today on earth, i submit.
      The Aviv barley is obsered in Israel to see If the next “New Moon” starts the 1st month and info is then passed around the world to those in exile today. Ephraim is the symbol leader of the so called “Lost Tribes” in exile. Ephraim will one day “Zion” with The House of Yahuda (judah) and be carried in one hand by YHVH, God, i submit. Do the 7 Appointed Times of Vayikrah (leviticus) Chapter 23 to “Get to know” this God and His Ways and this all becomes clear. The Mohadims or Feasts of YHVH are for us to remember what has happened and 3 Feasts in the Fall are for us to rehearse what has not yet happened so the key is the Aviv Barley observation to start planning the 7 Appointed Times of that year.

  • I’m trying to understand what Adar Bet is, or, more precisely, how it may fit into a prophetic application of an amount of time possibly being added to God’s calendar of events, as they are generally understood, if He perceives that the fields are not quite ready for the final harvest.

    Any thoughts on that?

    • Nathan Garrison says:

      First, You must find a Levite priest that can be trusted to ‘know and believe’ the Word of GOD. (its not as easy as You might think). Then, You must know that GOD entrusted this Priest to tell You when to start the year.

  • Charles Mickelson says:

    Rabbi Tovia Singer uses the rabbinic calendar as proof that the oral law is divine. He maintains that a lunar calendar would gradually lead us away from observing Pesach in the spring. Which we are biblically commanded to do. My question is: Is the ripening of the barley in Israel a divine regulator to keep us on track? And if so cannot this be mathematically verified?

    • Tom says:

      The Creator’s calendar is made to be observable by natural man using his natural senses and does not require math or science. The Abib barley is akin to a hard stop on a mechanical device to prevent error due to accumulated tolerances over a time span. in other words it’s a reset back to zero.

    • Tom says:

      I like Rabbi Singer and have chatted with him a couple of times. However, you answered your own question when you said ‘Rabbinic Calendar’ and not ‘Creator’s Calendar’. Something made by men is of religion. Religion is always the opinion of mortal men.

      • Nathan Garrison says:

        I am so happy to find a person that recognizes the ‘true value ‘ of religion

  • qfc7 says:

    Shalom Nehemia. We just concluded a wonderful Shabbat gathering in anticipation of the sighting of the renewed moon in Israel that unfortunately did not occur. Yahovah is in control obviously. But that was cool.

    The question did come up during our gathering today: where in Torah was the instruction given for Adar Bets and the month automatically beginning the next day if the renewed moon is not sighted on the day we believed it would be sighted but could not be sighted due to environmental hindrances such as cloud cover or haze? Where are these rules found in Torah? We turn to you because you have knowledge base for the biblical calendar. I’ve conducted a search of the internet for the answer to this nagging question, but have come up with nothing.

    Your help with this question would be greatly appreciated Nehemia

    Warmest Blessings

    • Great questions. Please check out my study Aviv Barley and the Spirit of Constantine. Solomon’s tax system had 12 tax officers and “one tax officer over the land”, which was understood since ancient times to be for leap years. Also, David and Jonathan knew “tomorrow is the new moon”. The simplest explanation is that the moon had not been sighted after the 29th day, so they knew it would be new moon the next day whether it was sighted or not. If they had 31+ day months, they could not have said “tomorrow is the new moon”.

      • Ely says:

        Shalom Nehemia
        In the reference you just provided, the scriptures only mentions 12 governors…not 13.
        “Solomon had twelve district governors over all Israel, who supplied provisions for the king and the royal household. Each one had to provide supplies for one month in the year”. 1 Kings 4:7-19

        Where is the 13th?…I’m trying to understand. Also the 2nd reference about David in 1 Samuel 20:18 there’s no reference to a 13th month neither. I can see what you mean by the fact that King David knew that the following day will be “chodesh”..but again..”chodesh” does not mean moon according to the biblical text. In fact what the text said is “hiNëh-chodesh” The new month it’s at hand, or behold new month.
        Again…I still believe there’s has to be another wait to identified the month. At the end, I dont see any of these rules of adding a 13th month in the biblical text. I need to see it. Please guide me to it. There has to be something tangible in scriptures rather that the traditions.

        Thanks again

        • 1 Kings 4:19 in Hebrew ends, “and one officer over the land.”

        • cgwaddell says:

          There’s proof for a 13th month in Ezekiel chapters 1-8. There’s a math formula.

          Ezekiel is commanded to lay on his side for 430 consecutive days. Then after that 430 days he meets in his house with the elders.

          There are dates given, totaling 1 year, 1 month and 23 days from the time Ezekiel started to lay on his side until he met with the elders. 430 days (at a minimum) can only be accounted for in the lunar calendar with a 13th month. The solar 365 or Enochian 364 day year leave you short. Only a 13 month lunar calendar can accommodate those days because that YEAR would have had to be a 13 month year. – see the short study at my site—- tfer DOT info —


        • markshano says:

          Ely – leviticus 23:1-30ish.. The lord told Moses and Moses told the Israelites, they must provide a first sheaf offering to start the new year. This can only be done in the spring when the barley is aviv, therefore the new year in ancient times began based on the harvest not the Rabbic calendar. Some times the first month for the new year would have to wait till the next new moon. (or 13th lunar month) Does that make sense?

      • Or that calulation was allready in use i think it was.

    • Rod i think the problem is trying to look for the sighting of the new moon.its not in the bible.surely it has to be at conjunction just because we cant see it does not mean its not there.conjunction can be calculated right to the minute today.calculation has been around for hundreds of years and is proven acurate.how could king david know that…TOMORROW IS THE NEW MOON. 1 sam 20:5 .there is no calendar in the bible as we undertand the calendar today.we know there are days months and years mentiond in it.i think genesis 1:14 might be a clue .the sun decides the day and the year. The moon decides the month.sometimes the crest of the moon can take hours or up to two days to be seen, which would only be about 13 days between sighting and full moon.i see a problem with useing sighting as the new moon.dont know if this helps.good luck in your search for bible truths

    • Devorah Arndt-Daniel says:

      Nehemia will be looking as soon as he gets to Israel and I am sure he will post reports. The “official” search is March 9th.
