The story is kind of amazing and is surprising to most christians because they have very little knowledge of the history of their own religion, But here goes. Pope Gregory, who set up the calendar we currently use (the Gregorian calendar) back dated the years to the birth of Jesus, but screwed it up. We currently live in the AD which is an abbreviation in Latin for "Year of Our Lord" and he dated Jesus, to year 1 AD, but the problem with that is Jesus was sought after by Herod the Great, and he died in the year 4 BC (Before Christ), so Jesus had to be born prior to 4 BC. The exact time of year is not really known, but judging by the fact of the story has the sheep out in the fields, it must have been spring. December 25, as someone put forth in a previous post stated, was taken from pagan celebrations, there were many at that time of year, the main one was the birthday of Mithras, that was on the exact day of December 25th, this was established by Constantine, because there was a lot of competition between the 2 belief systems, and he wanted christianity, to prevail., Saturnalia was the other main celebration, but it was a few days earlier on the solstice.
Nobody knows for sure exactly when he was born or died. Though it's almost certain he wasn't born in the winter (Christmas). ~~ And Christmas was actually "stolen" from Pagan worship, to try and make it easier to convert Pagans to Christianity.~~ Many scholars believe Jesus was actually born in the spring.
of coarse he was born in winter what ever walter1968 was talking about why would we (mormons) celabrate it if he wasnt. it isnt sure when he died but he was crucifed in between to theives. jew had him crucifed but now they worship him. some call them the Crist killers but they were just upset.
For the stars to align the way its stated in the Bible the date would have been closer to the 2nd week in September. The reason we celebrate His birthday on Dec. 25th is because there was no winter holiday. Halloween was the last holiday in the Fall and there was no holiday until Spring when Easter is celebrated. Unfortunately there is no discussion of stars in the Bible for when Jesus died so Astronomy doesn't help us with the date.
doth, As you can see there are several conflicting answers. That is how it is in the world when they ask the questions you asked. I would strongly suggest you do your own research. Today with the "net" it should not be too difficult. I guarantee you will be surprised at what you find and what you don't find.
