What Month is Abib in the Bible?

The Significance of Abib in Scripture

In the Torah, God instructs Moses and Aaron, “This month shall be your beginning of months; it shall be the first month of the year to you” (Exodus 12:2 NKJV). This month, known as Abib, became the start of the religious calendar for Israel. Abib marked a new year and a new beginning for God’s people after their Exodus deliverance.

Later in Israel’s history, after the Babylonian captivity, Abib became known as Nisan. We find this change in names in the book of Esther: “In the first month, which is the month of Nisan…” (Esther 3:7 NKJV). Though the name changed, Nisan held the same significance as the inaugural month on the Hebrew calendar.

The Exodus Connection

Abib is forever tied to the seminal Exodus event. Exodus 12 describes the first Passover observance, on the 10th day of Abib, and the subsequent Exodus from Egypt. Exodus 13:4 declares, “On this day you are going out, in the month Abib” (NKJV). The book of Deuteronomy also affirms, “Observe the month of Abib, and keep the Passover to the LORD your God, for in the month of Abib the LORD your God brought you out of Egypt by night” (Deuteronomy 16:1 NKJV).

By instituting Abib as the first month, God connected the Hebrew calendar with the Exodus and Passover for all time. Their deliverance became the new starting point for each year. As Moses indicated, this month of redemption was meant to be remembered and celebrated annually by God’s people.

The Spring Harvest Festivals

Abib kicked off a trio of pilgrimage festivals connected with the spring harvest. Exodus 23 directs: “And you shall observe… the Feast of Harvest, the firstfruits of your labors which you have sown in the field; and the Feast of Ingathering at the end of the year” (NKJV). The Feast of Unleavened Bread began on Abib 15, the Feast of Weeks (Harvest/Pentecost) came seven weeks later, and the Feast of Ingathering (Tabernacles/Booths) fell in the 7th month.

By situating Abib in the spring, these key festivals were synchronized with the agricultural cycle in the Promised Land. Barley and wheat were harvested in Abib and the following months. Dating Abib properly allowed God’s people to observe His feasts in tune with the seasons.

The Ripening of Barley

One way of confirming when Abib occurred was by inspecting the ripening stage of barley. The month was expressly tied with this grain’s maturity. Exodus 9:31 states, “…the barley was in the head and the flax was in bud” (NKJV). Deuteronomy 16:9 says, “You shall count seven weeks for yourself; begin to count the seven weeks from the time you begin to put the sickle to the grain.” The grain referenced would have been barley.

Leviticus 23 provides more detail: “When you come into the land which I give to you, and reap its harvest, then you shall bring a sheaf of the firstfruits of your harvest to the priest” (NKJV). This offering of firstfruits came from the newly ripened barley crop. Since barley ripened in spring, it cued the arrival of Abib. Spotting ripe barley indicated the “first month.”

Dating Clues From the Lunar Cycle

In addition to its agricultural and Exodus connections, the timing of Abib related to its place in the Hebrew lunar calendar. Twelve lunar months made up the year, with Abib situated as month one. Though there was fluctuation in the solar to lunar alignment, Abib consistently fell in the spring season.

The new moon marked the start of each month. As Roy Hoffman notes in his in-depth study, “Abib is a springtime month, occurring at the new moon nearest the spring equinox, either just before or just after.” The full moon halfway through the month would coincide with Passover and the Feast of Unleavened Bread.

Some Scriptural Support for a March-April Time Frame

Though the precise timing is difficult to pin down across centuries, Abib most likely fell sometime in March and April during Biblical history based on clues like spring ripened barley and counting from the new moon. Esther’s fast in the month of Nisan “in the twelfth month, which is the month of Adar” (Esther 3:7) also indicates Nisan followed shortly after a late winter month.

Several Scriptural hints also point to this general time frame. Exodus 13:4 describes the Israelites departing in the morning after the Passover night. This fits with the season of lengthening days after the March equinox. Exodus 16 details manna provision while in the Wilderness of Sin “on the fifteenth day of the second month after they had come out of the land of Egypt” (NKJV). Counting from an Abib departure puts this in mid-May, a reasonable time for manna before crops could be harvested.

Likewise, their arrival at Sinai to erect the tabernacle “on the first day of the first month in the second year” after leaving Egypt (Exodus 40:17) also fits in this springtime window. Overall, the scriptural evidence consistently points to a March to April timeframe for Abib and the associated festivals.

Theories and Perspectives on Dating Abib

Despite clues linking Abib with spring, the precise alignment with our modern solar calendar has been debated. Controversy stems from using different solar year starts or lunar cycles. Here we will examine three main theories on reckoning Abib.

The Spring Equinox View

This view looks for the new moon after the spring equinox to determine Abib. The equinox falls around March 21st each solar year marking spring in the Northern Hemisphere. Proponents like Solomon Zeitlin argue Abib should begin from the new moon closest to the equinox. This often falls in March but can slide into late April.

Critics claim this view disregards ripened barley evidence. In some years, barley may not be ready for weeks after the equinox if weather delays ripening. However, this approach has the advantage of using a consistent solar marker to date Abib. The spring equinox method recognizes fluctuations in agriculture while holding to a consistent astronomical event.

The Ripening Barley View

Many today support fixing Abib by the state of barley crops in Israel. Abib begins from the next new moon after spotting Aviv barley, meaning barley that has reached abib ripeness. Since barley ripens at different rates each year based on rain and temperatures, the month can start at different points in March or April accordingly.

Proponents argue this agricultural method adheres closest to scriptural directives. It accounts for actual crop conditions in Israel unlike the fixed equinox. Critics contend that tying Abib solely to barley leads to an unstable, wandering calendar not consistent year to year. But advocates respond that some variability in aligning solar and lunar years was inevitable.

The Fixed Calendar View

Many rabbinic Jewish calendars today utilize a precalculated, fixed calendar. This sets Nisan and the other months consistently from year to year, though initially tied to ripened barley. Adherents argue this provides needed calendar consistency, especially with Jews dispersed worldwide. Also, they contend that small errors from variable barley conditions accumulate over centuries without a fixed calendar.

Critics counter that a fixed calendar ignores Biblical agricultural directives and severs the tie of Abib with the Exodus. By decoupling the months from the moon and barley, it disregards original scriptural instructions. Despite its continuity benefits, a fixed calendar departs from the variable Biblical model centered around true Abib ripeness.

In assessing these prevailing theories, the barley evidence appears most reliable in determining Abib from Scripture. But a fixed calendar also offers advantages that potentially explain Jewish practice today. Perspectives vary on how closely the shifting cycles should be followed versus establishing a consistent calendar.

Why Getting Abib Right Matters

Getting the month of Abib right matters for correctly observing Passover, Unleavened Bread, and ultimately Firstfruits (Easter). Scripture warns that failing to celebrate Passover properly “shall be cut off from Israel” (Numbers 9:13). Esther’s festival date reckoning indicates the Jews carefully tracked these dates even in exile.

Christ’s crucifixion during Passover also shows the importance of proper Biblical dating. As Paul explains, “Christ, our Passover, was sacrificed for us” (1 Corinthians 5:7). Just as particpating in Passover allowed Israelites to escape death, so we rely on Christ’s atoning Passover sacrifice. Celebrating on God’s appointed feast days aligned with Abib remains relevant.

Prophetic Implications

Beyond the Exodus symbolism, Abib may hold prophetic significance for the future. In context of the end times, Daniel 12 notes, “Blessed is he who waits, and comes to the 1335 days” (NKJV). Intriguingly, 1335 days from Tishri 1 lands very near Abib 1. This potential connection suggests that Abib’s role in redemptive history may extend into future prophetic fulfillment surrounding Christ’s return.

Determining the month of Abib each year carries important religious and agricultural meaning. Whether its timing shifts with the barley harvest or is fixed on the calendar, recognizing Abib ushers in a time of redemption and hope for God’s people. By learning its history and significance, we can more fully appreciate its continuing relevance in Scripture and practice.


The month of Abib marked a pivotal new beginning and season of redemption for Israel at the Exodus. Understanding its timing in the Bible helps in properly celebrating Passover today. Though some uncertainty exists around exactly matching it with modern calendars, contextual clues strongly indicate Abib falls in our March-April time frame.

Determining Abib by spring barley ripening makes important connections with Scripture and seasonal harvest festivals. Its agricultural and redemptive symbolism point to God’s plan of salvation and ultimate restoration. Whether variable or fixed, establishing the month of Abib each year keeps God’s appointed times central. Just as Israel never forgot their Exodus redemption, remembering Abib directs our focus to God’s mighty acts past, present, and future.
