A Comparison Between the Biblical and Gregorian Calendars
The Biblical (Jewish) calendar is a lunar-solar calendar, meaning its months are based on the moon’s cycles, but it adjusts to align with the solar year. In contrast, the Gregorian calendar (introduced by the Romans) is a purely solar calendar. Because of this difference, the Biblical months don’t line up exactly with January–December and instead shift slightly each year.
Here’s how the Biblical months correspond to the modern Gregorian calendar:
Key Differences Between the Biblical & Gregorian Calendar
Biblical Months Start with the New Moon 🌙 – Unlike the fixed-length Gregorian months, Biblical months begin when the new moon is sighted.
The New Year Begins in Spring, Not Winter 🌱 – The Biblical New Year (Nisan 1) happens in March/April, not in January.
The Biblical Calendar Has Leap Months 📆 – Since the lunar year is ~11 days shorter than the solar year, a 13th month (Adar II) is added every few years to realign the calendar with the seasons.
God’s Time Revolves Around Agricultural Cycles 🌾 – The Biblical months correspond to farming seasons:
Seed Time begins in Nisan (spring).
Harvest Time begins in Tishrei (fall).
Rainy Season follows Sukkot (October–March).
Why Understanding the Biblical Calendar Matters
Many Christians and Jewish believers in Yeshua are rediscovering the Biblical calendar because it connects us to God’s appointed times, His creation, and the rhythms of Scripture. Understanding it helps us align our lives with the Biblical cycles instead of the man-made Roman calendar.
Rediscovering the Biblical calendar helps us:
✅ Align our lives with God’s appointed times (Leviticus 23)
✅ Celebrate the Feasts and Biblical rhythms with intention
✅ Recognize the agricultural and prophetic patterns in Scripture
✅ Deepen our connection to God’s timing instead of modern man-made systems
