The Jewish calendar months of Jesus's incarnation and birth
The Calendar Months
Christmas celebration, as a Christian religious feast honoring the birth of Jesus Christ, proves that there is no kind of data, no reasoning skill, no intellect genius that can bring a mind to believe in the God of Abraham, Isaac, and Jacob. For example, the data in Luke 1:26 is very obvious to compel the intellect to conclude that Christmas is a religious hoax. But the mind that understands the data in Luke 1:26 is compelled to agree that Jesus could not have been born on the 25th of December, states that he still celebrates not Christmas but the birth of Jesus, reasoning that the date does not matter. That would have been absolutely true if Mark 7:7 did not interject a warning about teachings of anything that lacks the backing support the biblical data of the kind of Luke 1:26.
Mark 7:6-7 LITV
(6) And answering, He said to them, Well did Isaiah prophesy concerning you, hypocrites; as it has been written: "This people honors Me with the lips, but their heart is far away from Me;
(7) and in vain they worship Me, teaching as doctrines the commandments of men." Isaiah 29:13
Upon reading Luke 1:26 & 42 and visualizing the table of the Jewish calendar month, we can see that John the Baptist could have been born in December but for Jesus, it is by end of May towards beginning of June. The table does not take into account the addition of an intercalary month that would still lengthen the Jewish year.
