Did you know that the biblical calendar differs from the commonly used Roman calendar? What are both based on? How do they differ? When does the Bible teach the first month of the year is? What are the names of the biblical months and when do they fall? Did Hillel II invent the 'calculated' calendar in the fourth century or simply make the rules public? Did Jesus use a calculated calendar? What about the date of His final Passover and His execution? Dr. Thiel addresses these questions as well as shows a chart of when God's Holy Days fall on the Roman calendar.
