I haven't had to explain yet what the "true meaning" of Christmas is to the kids, and really dont know what I will tell them when they ask...its Christian roots arn't important to me, but it is the basis of Xmas I suppose...
Nards, Christmas doesn't actually have any Christian roots at all. The history of Christmas dates back over 4000 years. Many of our Christmas traditions were celebrated centuries before the Christ child was born. The 12 days of Christmas, the bright fires, the yule log, the giving of gifts, carnivals(parades) with floats, carolers who sing while going from house to house, the holiday feasts, and the church processions can all be traced back to the early Mesopotamians.
Many of these traditions began with the Mesopotamian celebration of New Years. The Mesopotamians believed in many gods, and as their chief god - Marduk. Each year as winter arrived it was believed that Marduk would do battle with the monsters of chaos. To assist Marduk in his struggle the Mesopotamians held a festival for the New Year. This was Zagmuk, the New Year's festival that lasted for 12 days.
The Mesopotamian king would return to the temple of Marduk and swear his faithfulness to the god. The traditions called for the king to die at the end of the year and to return with Marduk to battle at his side.
To spare their king, the Mesopotamians used the idea of a "mock" king. A criminal was chosen and dressed in royal clothes. He was given all the respect and privileges of a real king. At the end of the celebration the "mock" king was stripped of the royal clothes and slain, sparing the life of the real king.
The Persians and the Babylonians celebrated a similar festival called the Sacaea. Part of that celebration included the exchanging of places, the slaves would become the masters and the masters were to obey.
Early Europeans believed in evil spirits, witches, ghosts and trolls. As the Winter Solstice approached, with its long cold nights and short days, many people feared the sun would not return. Special rituals and celebrations were held to welcome back the sun.
In Scandinavia during the winter months the sun would disappear for many days. After thirty-five days scouts would be sent to the mountain tops to look for the return of the sun. When the first light was seen the scouts would return with the good news. A great festival would be held, called the Yuletide, and a special feast would be served around a fire burning with the Yule log. Great bonfires would also be lit to celebrate the return of the sun. In some areas people would tie apples to branches of trees to remind themselves that spring and summer would return.
The ancient Greeks held a festival similar to that of the Zagmuk/Sacaea festivals to assist their god Kronos who would battle the god Zeus and his Titans.
The Roman's celebrated their god Saturn. Their festival was called Saturnalia which began the middle of December and ended January 1st. With cries of "Jo Saturnalia!" the celebration would include masquerades in the streets, big festive meals, visiting friends, and the exchange of good-luck gifts called Strenae (lucky fruits).
The Romans decked their halls with garlands of laurel and green trees lit with candles. Again the masters and slaves would exchange places
"Jo Saturnalia!" was a fun and festive time for the Romans, but the Christians though it an abomination to honor the pagan god. The early Christians wanted to keep the birthday of their Christ child a solemn and religious holiday, not one of cheer and merriment as was the pagan Saturnalia.
But as Christianity spread they were alarmed by the continuing celebration of pagan customs and Saturnalia among their converts. At first the Church forbid this kind of celebration. But it was to no avail. Eventually it was decided that the celebration would be tamed and made into a celebration fit for the Christian Son of God.
Some legends claim that the Christian "Christmas" celebration was invented to compete against the pagan celebrations of December. The 25th was not only sacred to the Romans but also the Persians whose religion Mithraism was one of Christianity's main rivals at that time. The Church eventually was successful in taking the merriment, lights, and gifts from the Saturanilia festival and bringing them to the celebration of Christmas.
The exact day of the Christ child's birth has never been pinpointed. Traditions say that it has been celebrated since the year 98 AD. In 137 AD the Bishop of Rome ordered the birthday of the Christ Child celebrated as a solemn feast. In 350 AD another Bishop of Rome, Julius I, choose December 25th as the observance of Christmas.

Jesus' birth
The Bible gives no straight answer to the date of Jesus' birth, but it does give clues. Luke 2:8–14 speaks of shepherds living outdoor and tending to a flock of sheep. The text reads, "And there were in the same country shepherds abiding in the field, keeping watch over their flock by night." Scholars of the Bible have concluded that this would be highly unlikely in the month of December, for the weather conditions would be too cold to live outside or tend to a flock of sheep. In addition, it is also unlikely that Caesar would force Jews to trek to their home cities under the cold and rainy seasons.
Why do people celebrate Jesus' birth on December 25?
The answer to this question lies in the pagan (the ancient polytheistic religion) origins of Christmas. Before the Romans converted to Christianity, they celebrated the popular holiday Saturnalia, a festival of feasting and revelry held in December in celebration of Saturn, the god of agriculture, and the winter solstice.
Kelly Wittmann wrote, "In 350, Pope Julius I declared that Christ's birth would be celebrated on December 25. There is wide acceptance of the belief that Pope Julius I was trying to make it as painless as possible for pagan Romans, who remained a majority at that time, to convert to Christianity. The new religion went down a bit easier, knowing that their feasts would not be taken away from them." Moreover, in ancient Babylon, December 25 was the feast of the Son of Isis, Goddess of Nature, was celebrated with, "Raucous partying, gluttonous eating and drinking, and gift-giving were traditions of this feast", as stated by Kelly Wittmann.
A popular theory as to why the Church would pick December 25th is that the Feast of the Annunciation had previously been set to March 25. This is the celebration of the conception of Jesus in the womb of Mary at the time she was visited by the angel Gabriel. The fixing of December 25 for Christmas would support the conclusion that the Church set the date of the Nativity as nine months from that point.

The middle of winter has long been a time of celebration around the world. Centuries before the arrival of the man called Jesus, early Europeans celebrated light and birth in the darkest days of winter. Many peoples rejoiced during the winter solstice, when the worst of the winter was behind them and they could look forward to longer days and extended hours of sunlight.
In Scandinavia, the Norse celebrated Yule from December 21, the winter solstice, through January. In recognition of the return of the sun, fathers and sons would bring home large logs, which they would set on fire. The people would feast until the log burned out, which could take as many as 12 days. The Norse believed that each spark from the fire represented a new pig or calf that would be born during the coming year.
The end of December was a perfect time for celebration in most areas of Europe. At that time of year, most cattle were slaughtered so they would not have to be fed during the winter. For many, it was the only time of year when they had a supply of fresh meat. In addition, most wine and beer made during the year was finally fermented and ready for drinking.
In Germany, people honored the pagan god Oden during the mid-winter holiday. Germans were terrified of Oden, as they believed he made nocturnal flights through the sky to observe his people, and then decide who would prosper or perish. Because of his presence, many people chose to stay inside.

The same applies for all Christian "traditions" eg Easter which have all been stolen from pagan and ancient cultures and beliefs. So even if you're not religious like me, you can still celebrate the REAL meaning of Christmas which is eating, drinking and having a good time.
