Though different sources have varied theories on the actual date of his birth, most agree Dec. 25 is not the actual birthday of Jesus.

From www.bible.ca: "The exact date of Jesus' birth is a mystery. About the best we can do is to narrow it down to seasons. The Bible does give us one clue. The shepherds were in the fields with their flocks at night when Jesus was born. This clearly indicates that Jesus was born during the warmer seasons. During the coldest months like December or January, the shepherds didn't sleep in the fields but would bring their flocks into corals. There is virtual agreement among scholars that December 25 is not the birth date, not even the month that Jesus was born."

From the Wikipedia page on Christmas: " It is celebrated on December 25, but this date is not known to be Jesus' actual birthday, and may have initially been chosen to correspond with either the day exactly nine months after some early Christians believed Jesus had been conceived, a historical Roman festival,8 or the date of the northern hemisphere's winter solstice."

From christiananswers.net: "Was Jesus born on December 25, or in December at all? Although it’s not impossible, it seems unlikely. The Bible does not specify a date or month. One problem with December is that it would be unusual for shepherds to be “abiding in the field” at this cold time of year when fields were unproductive. The normal practice was to keep the flocks in the fields from Spring to Autumn. Also, winter would likely be an especially difficult time for pregnant Mary to travel the long distance from Nazareth to Bethlehem (70 miles).

Jesus was not really born of December 25th, it was just proclaimed as his birth date based on traditional pagan beliefs not on solid evidence. The purpose of declaring such date as Jesus birth date, was to make Christianity acceptable to the pagans and hasten the spread of Christianity.

"There is no evidence for this date. So then, who decided that Jesus' birth would be celebrated on that date? The early Christian church did not celebrate Jesus' birth. It wasn't until A.D. 440 that the church officially proclaimed December 25 as the birth of Christ. This was not based on any religious evidence but on a pagan feast. Saturnalia was a tradition inherited by the Roman pagans from an earlier Babylonian priesthood. December 25 was used as a celebration of the birthday of the sun god. It was observed near the winter solstice.

The apostles in the Bible predicted that some Christians would adopt pagan beliefs to enable them to make their religion more palatable to the pagans around them. Therefore, some scholars think the church chose the date of this pagan celebration to interest them in Christianity. The pagans were already used to celebrating on this date."

I'm gonna hazard a guess he was born around March/April in the sign of Aries the Ram, as he was called the lamb of God, also considered as a sacrificial lamb, with many of these references.

There are dozens of interesting sites trying to hack this question, which is relatively trivial, but generates much comment.

Quote: "Historical records and modern-day computer simulations indicate that there was a rare series of planetary groupings, also known as conjunctions, during the years 3 B.C. and 2 B.C.

Step 3: Retracing the conjunctions
The show started on the morning of June 12 in 3 B.C., when Venus could be sighted very close to Saturn in the eastern sky. Then there was a spectacular pairing of Venus and Jupiter on Aug. 12 in the constellation Leo, which ancient astrologers associated with the destiny of the Jews.

Between September of 3 B.C. and June of 2 B.C., Jupiter passed by the star Regulus in Leo, reversed itself and passed it again, then turned back and passed the star a third time. This was another remarkable event, since astrologers considered Jupiter the kingly planet and regarded Regulus as the “king star.”

The crowning touch came on June 17, when Jupiter seemed to approach so close to Venus that, without binoculars, they would have looked like a single star."

While these events could point to either the time of birth or conception, I think the following researcher finds the time pointing to Spring (as biblical accounts say there were shepherds tending flocks at pasture--which they aren't doing in winter when sheep are in stables.)

Quote: "On April 17, 6 BC two years before King Herod died Jupiter emerged in the east as a morning star in the sign of the Jews, Aries the Ram. The account in Matthew refers twice to the Star being in the east with good reasons. When the royal star of Zeus, the planet Jupiter, was in the east this was the most powerful time to confer kingships. Furthermore, the Sun was in Aries where it is exalted. And the Moon was in very close conjunction with Jupiter in Aries. Modern calculations suggest that this was close enough to be an occultation (eclipse). But the Sun’s glare would have hidden that event. Saturn was also present which meant that the three rulers of Aries’ trine (Sun, Jupiter, and Saturn) were present in Aries. Saturn and Jupiter were said to be "attendants" on the rising Sun, another regal aspect for astrologers. By modern expectations this is trivial, but for ancient stargazers this configuration was truly awesome."

As a comparison, the Sabbath, which was observed by Jesus and is mandated as a weekly day of rest in the Ten Commandments, was ignored by the early church fathers, and they made Sunday the Christian day of observance, and Christmas falls on a day of many pagan festivals, in accordance with Roman custom also, which is also the WInter solstice, the shortest day of the year.

Although there is no written or any other form of record which proves that Jesus was born on 25th December, but I believe that it is very likely to be true. Billions of people have been believing on this for ages and their belief just cannot be a mere myth.

Not believing on something just because no proof has been found so far, does not make it false. If this date is being passed on from generations to generations, it is very likely that it was true.

Believing and trying to reach the truth is a scientific approach, while disbelief is most unscientific.

May be that people some day will be able to prove it.

Finally, I would ask why not to believe it? If there is no proof that it is true, there is no proof either that it is false. So, it should be given a benefit of doubt.

Thanks

No Jesus wasn't born on December 25th because the hills of Judea was too much snow.Shepherds couldn't travel in the snow.Christ types the lamb and lambs are born in the spring. It is the sun Gods birthday and the Catholics decided to make it Jesus's Birthday.Thats why it is called a pagan holiday. He was born in the spring.between April and May.

Your question is a difficult one to answer in any absolute sense. There is no archeological proof Jesus was a real live person, so from a purely archeological sense it is meaningless to ask this question. From a historic perspective, i.e. what is widely accepted as historical truth, the answer is yes, because that's when the Christian world celebrates Christmas. So the bottom line answer is at the same time that the question cannot be answered except from a religious perspective, and from that perspective the answer is yes.

Probably not (the exact date of his birth is not known). Christmas Day 12/25 is a day chosen to honor his birth. There are also different religions that celebrate his birthday on other dates.

My understanding is that Jesus (aka Jesheua Sananda Melchizedek) was actually born on November 22, 12BC "of natural conception" to Essence parents Jeudi and Joehius, "in the private dwelling of Ben-Yumen (later mistranslated as 'Benjamin'). The birth was "attended by Saradi, half-sister of Jeudi and wife of Ben-Yumen, Merigedra, daughter of Saradi and Ben-Yumen, Immanuel, brother of Merigedra and the Melchizedek Cloister High Priest that became known as 'John the Bapstist'."
