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 moon’s 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. •Focus: The Biblical Calendar and How to Determine It. • 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. • Practical Application: o Understanding how to observe Elohim’s appointed times and festivals in their proper seasons. o The importance of trusting Elohim’s 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 moon for months and the solar year for seasons. This calendar is based on the cycles of the moon, with months determined by the moon’s 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 moon (חֶדֶשׁ), which marks the start of a new month (Genesis 1:14-19).
Weeks: The week (שָׁבוּעַ) is a set seven-day period, with the seventh day being the Sabbath (שַׁבָּת), a day of rest (Exodus 20:8-11).
Years: The biblical year (שָׁנָה) 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 Nisan (נִיסָן), also known as Aviv (אָבִיב), which marks the beginning of the sacred year. Nisan is significant because it is the month in which Passover (פסח) occurs, making it one of the most important months in the biblical calendar. Determining the start of Nisan 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 Nisan is determined by the new moon (חֶדֶשׁ) closest to the spring equinox (usually around March 20-21 in the Gregorian calendar). This marks the beginning of Nisan and sets the stage for the festivals.
Passover (פסח) occurs on the 14th of Nisan, with Unleavened Bread (חַג הַמַּצּוֹת) beginning on the 15th (Exodus 12:2-3, Leviticus 23:5-6).
Check for Aviv (Ripening Barley):
The month of Nisan cannot begin until the barley in Israel is in the Aviv (ripening) stage. Aviv refers to the stage in which the barley is ripened enough to be used for the Omer offering (מִנְחַת הָעֹמֶר), the first fruits of the barley harvest, which begins the counting of the omer leading to Shavuot (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 Aviv (ready to be harvested) would they declare that the first month (Nisan) had begun.
If the barley was not yet Aviv, the beginning of Nisan would be delayed by a month, making that year a leap year with an added Adar II (אֲדָר שֵׁנִי) to adjust the calendar (Exodus 9:31-32, Deuteronomy 16:1-2).
Scriptural Confirmation:
Exodus 12:2 – "This month shall be for you the beginning of months. It shall be the first month of the year for you."
Deuteronomy 16:1 – "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 23:15 – "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 - פסח) occurs on the 14th of Nisan, and this event is central to the biblical calendar. Following Passover, the Feast of Unleavened Bread (חַג הַמַּצּוֹת) lasts for seven days, beginning on the 15th of Nisan (Exodus 12:6, Leviticus 23:6).
Other significant festivals such as Shavuot (Feast of Weeks), Rosh Hashanah (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 month (Adar II) in certain years, ensuring that the biblical festivals stay in their proper seasonal context.
The Metonic cycle (מַעְגַּל הַמֵּטוֹנִי) is used to determine when a leap month is added. The Metonic cycle 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 Elohim’s appointed times:
Passover (Pesach - פֶּסַח) – 14th of Nisan
Commemorates the Exodus from Egypt and the sacrifice of the Passover lamb (Exodus 12:1-14).
Feast of Unleavened Bread (חַג הַמַּצּוֹת) – 15th to 21st of Nisan
Celebrates the Israelites' hasty departure from Egypt, which did not allow time for their bread to rise (Exodus 12:15-20).
First Fruits (Omer - מִנְחַת הָעֹמֶר) – 16th of Nisan (Day after the weekly Sabbath during Unleavened Bread)
The offering of the first fruits of the barley harvest, starting the counting of the omer towards Shavuot (Leviticus 23:10-14).
Feast of Weeks (Shavuot - שָׁבוּעַ) – 50 days after First Fruits (counted during the omer)
Celebrates the giving of the Torah at Mount Sinai (Exodus 34:22, Leviticus 23:15-21).
Feast of Trumpets (Rosh Hashanah - רֹאשׁ הַשָּׁנָה) – 1st of Tishrei
The beginning of the civil year, marked by the blowing of trumpets to usher in the new year (Leviticus 23:23-25).
Day of Atonement (Yom Kippur - יוֹם כִּפּוּר) – 10th of Tishrei
A day of fasting, repentance, and seeking forgiveness (Leviticus 16:29-34, Leviticus 23:26-32).
Feast of Tabernacles (Sukkot - סֻכּוֹת) – 15th to 22nd of Tishrei
Celebrates the Israelites’ wilderness wanderings and living in temporary shelters (Leviticus 23:33-43).
Shemini Atzeret (שְׁמִינִי עֲצֶרֶת) – 22nd of Tishrei
A final day of the Feast of Tabernacles (Leviticus 23:36).
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 Aviv (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 Nisan (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 cycle 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 Passover and Sukkot. The full moon marks the middle of the month, and these festivals are celebrated based on this cycle.
The Feast of Tabernacles (Sukkot - סֻכּוֹת), 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 moon 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.
