Introduction to the Hebrew Calendar

The Hebrew calendar is a lunisolar calendar, meaning it aligns with both the moon (lunar) and the sun (solar). It has 12 months, with some years having 13 months (leap years). Understanding Hebrew months is essential for reading biblical dates and understanding Jewish festivals.

Key Insight: The Hebrew calendar begins in the month of Tishrei (around September/October), which is when Rosh HaShanah (the Jewish New Year) occurs. However, the biblical year originally began in Nisan (around March/April), the month of Passover. The months alternate between 29 and 30 days, and a leap month (Adar II) is added approximately every 3 years to keep the calendar aligned with the solar year.

Biblical vs. Modern Month Names

In the Bible, months were often numbered rather than named. The modern Hebrew month names come from the Babylonian calendar, adopted during the exile:

Biblical Numbering System

In the Bible, months are often referred to by number:

First month: Nisan (נִיסָן) - "the month of Aviv" (Exodus 12:2)

Second month: Iyar (אִיָּר) - "the second month" (Genesis 7:11)

Seventh month: Tishrei (תִּשְׁרֵי) - "the seventh month" (Leviticus 23:24)

Note: The biblical year began in Nisan (the month of Passover), but the modern Jewish calendar year begins in Tishrei (Rosh HaShanah).

Modern Hebrew Month Names

The modern names come from Babylonian origins:

Most Hebrew month names (Tishrei, Cheshvan, Kislev, Tevet, Shevat, Adar, Nisan, Iyar, Sivan, Tammuz, Av, Elul) were adopted from the Babylonian calendar during the Babylonian exile (6th century BCE). These names appear in post-exilic biblical books like Esther, Nehemiah, and Zechariah.

The Hebrew Calendar System

The Hebrew calendar is a lunisolar calendar with unique features:

Lunisolar Calendar

The Hebrew calendar follows both the moon (lunar) and the sun (solar). Each month begins with the new moon (Rosh Chodesh), but the year is adjusted to align with the solar year through leap months.

Leap Years

Approximately every 3 years, a 13th month (Adar II) is added to keep the calendar aligned with the seasons. This ensures that Passover always occurs in the spring and other festivals occur in their proper seasons.

Rosh Chodesh (New Month)

רֹאשׁ חֹדֶשׁ

Rosh Chodesh

"Head of the month" - The beginning of each Hebrew month, marked by the new moon. This was a significant time in biblical Israel (Numbers 10:10, 28:11-15).

Biblical Significance of Hebrew Months

Many Hebrew months are associated with important biblical events and festivals:

Nisan (נִיסָן) - The Month of Passover

הַחֹדֶשׁ הַזֶּה לָכֶם רֹאשׁ חֳדָשִׁים

Hachodesh hazeh lakhem rosh chodashim

"This month shall be for you the beginning of months" (Exodus 12:2)

Nisan is the first month of the biblical year and the month of Passover, when the Israelites were delivered from Egypt.

Tishrei (תִּשְׁרֵי) - The Month of Rosh HaShanah

בַּחֹדֶשׁ הַשְּׁבִיעִי בְּאֶחָד לַחֹדֶשׁ

Bachodesh hashvi'i be'echad lachodesh

"In the seventh month, on the first day of the month" (Leviticus 23:24)

Tishrei is the seventh month of the biblical year but the first month of the modern Jewish calendar year. It contains Rosh HaShanah, Yom Kippur, and Sukkot.
