The biblical calendar is rooted in the principles established in the Scriptures, particularly the Torah (the first five books of the Bible). Understanding how to properly determine and follow the biblical calendar requires an in-depth understanding of the moonโs cycles, the seasonal festivals, and the specific commands given by Elohim (God) to Israel. Below is a comprehensive guide on how to determine the biblical calendar, the significance of the first month (Nisan), and the involvement of the Aviv (ripening barley) in determining the start of the year, along with all the biblical feasts.
โขFocus: The Biblical Calendar and How to Determine It.
โข Key Concepts:
o The lunar-solar nature of the biblical calendar.
o The significance of the new moon and the Aviv barley in determining the first month of the year.
o The festivals and their alignment with the cycles of the moon.
o The role of leap years in adjusting the calendar to maintain seasonal alignment.
โข Practical Application:
o Understanding how to observe Elohimโs appointed times and festivals in their proper seasons.
o The importance of trusting Elohimโs timing in both the natural and spiritual realms.
o Aligning one’s life and faith with the divine calendar as outlined in Scripture.
The Basis of the Biblical Calendar
The biblical calendar is primarily a lunar-solar calendar, meaning that it relies on both the phases of the moonย for months and the solar yearย for seasons. This calendar is based on the cycles of the moon, with months determined by the moonโs phases, and the year being synchronized with the solar year through adjustments such as leap months.
Key Elements:
-
Months: Each month begins with the new moonย (ืึถืึถืฉื), which marks the start of a new month (Genesis 1:14-19).
-
Weeks: The weekย (ืฉึธืืืึผืขึท) is a set seven-day period, with the seventh day being the Sabbathย (ืฉึทืืึผึธืช), a day of rest (Exodus 20:8-11).
-
Years: The biblical yearย (ืฉึธืื ึธื) is based on the solar year, roughly 365.24 days, with adjustments to account for the difference between lunar months and the solar year (Exodus 12:2).
Understanding the First Month: Nisan (Aviv)
The first month of the biblical year is Nisanย (ื ึดืืกึธื), also known as Aviv (ืึธืึดืื), which marks the beginning of the sacred year. Nisanย is significant because it is the month in which Passoverย (ืคืกื) occurs, making it one of the most important months in the biblical calendar. Determining the start of Nisanย is essential, and it requires a method that combines both the lunar cycle and the ripening of the barley.
How to Determine Nisan (Aviv) Using the Lunar-Solar Calendar and Aviv Barley:
-
Look for the New Moon Closest to the Spring Equinox:
-
The start of Nisanย is determined by the new moonย (ืึถืึถืฉื) closest to the spring equinox (usually around March 20-21 in the Gregorian calendar). This marks the beginning of Nisanย and sets the stage for the festivals.
-
Passover (ืคืกื) occurs on the 14th of Nisan, with Unleavened Breadย (ืึทื ืึทืึทึผืฆึผืึนืช) beginning on the 15th (Exodus 12:2-3, Leviticus 23:5-6).
-
-
Check for Aviv (Ripening Barley):
-
The month of Nisanย cannot begin until the barley in Israel is in the Aviv (ripening) stage. Avivย refers to the stage in which the barley is ripened enough to be used for the Omer offeringย (ืึดื ึฐืึทืช ืึธืขึนืึถืจ), the first fruits of the barley harvest, which begins the counting of the omer leading to Shavuotย (Feast of Weeks).
-
In biblical times, witnesses would go to the field to inspect the barley crop. Only when the barley was deemed to be Avivย (ready to be harvested) would they declare that the first month (Nisan) had begun.
-
If the barley was not yet Aviv, the beginning of Nisanย would be delayed by a month, making that year a leap year with an added Adar IIย (ืึฒืึธืจ ืฉืึตื ึดื) to adjust the calendar (Exodus 9:31-32, Deuteronomy 16:1-2).
-
Scriptural Confirmation:
-
Exodus 12:2ย โ “This month shall be for you the beginning of months. It shall be the first month of the year for you.”
-
Deuteronomy 16:1ย โ “Observe the month of Abib (Aviv), 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.”
-
Exodus 23:15ย โ “Celebrate the Feast of Unleavened Bread; for seven days eat bread made without yeast, as I commanded you. Do this at the appointed time in the month of Aviv, for in that month you came out of Egypt.”
The Role of Passover and Festivals:
-
Passover (Pesach – ืคืกื) occurs on the 14th of Nisan, and this event is central to the biblical calendar. Following Passover, the Feast of Unleavened Breadย (ืึทื ืึทืึทึผืฆึผืึนืช) lasts for seven days, beginning on the 15th of Nisan (Exodus 12:6, Leviticus 23:6).
-
Other significant festivals such as Shavuotย (Feast of Weeks), Rosh Hashanahย (Feast of Trumpets), Yom Kippur, and Sukkot (Feast of Tabernacles) follow the same lunar-solar alignment to ensure proper observance at their appointed times (Leviticus 23:23-44, Numbers 29:1-39).
Leap Year Adjustments and the Solar-Lunar Cycle:
Because the lunar year (about 354 days) is shorter than the solar year (about 365.24 days), the biblical calendar must be adjusted to keep the festivals aligned with the correct seasons. This is done by adding a leap monthย (Adar II) in certain years, ensuring that the biblical festivals stay in their proper seasonal context.
-
The Metonic cycleย (ืึทืขึฐืึทึผื ืึทืึตึผืืึนื ึดื) is used to determine when a leap month is added. The Metonic cycleย is a 19-year cycle that ensures the lunar months align with the solar year.
-
The leap month is added 7 times in a 19-year cycle, ensuring that the biblical festivals remain aligned with the correct seasons.
List of All Biblical Feasts:
The biblical calendar includes the following feasts, which are significant for observing Elohimโs appointed times:
-

Summary of How to Determine the Biblical Year:
To determine the first month (Nisan/Aviv) of the biblical year:
-
Look for the new moon that appears closest to the spring equinox (around March 20-21).
-
Ensure the barley is Avivย (ready for harvest), which confirms that Nisan can begin (Exodus 9:31-32, Deuteronomy 16:1-2).
-
This marks the start of Nisan, the first month of the biblical year.
-
Passover (Pesach) occurs on the 14th of Nisan, and Unleavened Bread begins on the 15th of Nisanย (Exodus 12:6-17, Leviticus 23:6).
-
The lunar months continue from this point, with the other festivals falling in their appointed times.
-
Leap years are adjusted using the Metonic cycleย to ensure the months and festivals stay aligned with the solar year.
The Impact of the Full Moon and Festivals:
Many of the biblical festivals are tied to the full moon, particularly Passoverย and Sukkot. The full moon marks the middle of the month, and these festivals are celebrated based on this cycle.
-
The Feast of Tabernaclesย (Sukkot – ืกึปืึผืึนืช), like Passover, is celebrated on the 15th of the month, ensuring that it too aligns with the full moon (Leviticus 23:33-43).
Conclusion
Understanding how to determine the first month of the biblical calendar and how to observe the feasts and festivals properly is critical for believers today. By following the lunar-solar calendar, which begins with the new moonย closest to the spring equinox, and ensuring that leap years are accounted for, the biblical calendar stays true to the Scriptures and ensures that the festivals remain in the correct seasons.
The first month (Nisan) begins with the new moon after the spring equinox, and Passoverย (Pesach) is celebrated on the 14th of Nisan. This method ensures the alignment of all biblical feasts and upholds the divine timing established in the Torah. By understanding this calendar, believers can more fully honor Elohimโs appointed times and better align their lives with His divine plan.
The first month (Nisan) begins with the new moon closest to the spring equinox, and Passoverย (Pesach) is celebrated on the 14th of Nisan.
