Christmas is celebrated to remember the birth of of Jesus Christ, who Christians believe is the Son of God.
The name "Christmas" originates from the Mass of Christ (or Jesus). A Mass administration (which is some of the time called Communion or Eucharist) is the place Christians recollect that Jesus passed on for us and after that returned to life. The 'Christ-Mass' administration was the stand out that was permitted to happen after nightfall (and before dawn the following day), so individuals had it at Midnight! So we get the name Christ-Mass, abbreviated to Christmas.
Christmas is currently celebrated by individuals around the globe, whether they are Christians or not. It's a period when family and companions meet up and recollect the great things they have. Individuals, and particularly kids, additionally like Christmas as it's a period when you give and get presents!
Nobody knows the genuine birthday of Jesus! No date is given in the Bible, so why do we praise it on the 25th December? The early Christians surely had numerous contentions in the matter of when it ought to be praised! Additionally, the conception of Jesus most likely didn't happen in the year 1AD yet somewhat prior, some place somewhere around 2BC and 7BC (there isn't a 0AD - the years go from 1BC to 1AD!).
The initially recorded date of Christmas being praised on December 25th was in 336AD, amid the season of the Roman Emperor Constantine (he was the first Christian Roman Emperor). A couple of years after the fact, Pope Julius I formally pronounced that the conception of Jesus would be commended on the 25th December.
There are a wide range of customs and speculations in respect to why Christmas is praised on December 25th. An early Christian convention said that the day when Mary was informed that she would have an exceptionally extraordinary child, Jesus (called the Annunciation) was on March 25th -'s despite everything it commended today on the 25th March. Nine months after the 25th March is the 25th December! Walk 25th was additionally the day some early Christians thought the world had been made, furthermore the day that Jesus kicked the bucket on when he was a grown-up.
December 25th may have likewise been picked on the grounds that the Winter Solstice and the antiquated agnostic Roman midwinter celebrations called "Saturnalia" and 'Bites the dust Natalis Solis Invicti' occurred in December around this date - so it was a period when individuals officially praised things.
The Winter Solstice is the day where there is the shortest time between the sun rising and the sun setting. It happens on December 21st or 22nd. To pagans this meant that the winter was over and spring was coming and they had a festival to celebrate it and worshipped the sun for winning over the darkness of winter. In Scandinavia, and some other parts of northern Europe, the Winter Solstice is known as Yule and is where we get Yule Logs from. In Eastern europe the mid-winter festival is called Koleda.
The Roman Festival of Saturnalia took place between December 17th and 23rd and honoured the Roman god Saturn. Dies Natalis Solis Invicti means 'birthday of the unconquered sun' and was held on December 25th (when the Romans thought the Winter Solstice took place) and was the 'birthday' of the Pagan Sun god Mithra. In the pagan religion of Mithraism, the holy day was Sunday and is where get that word from!
Early Christians might have given this festival a new meaning - to celebrate the birth of the Son of God 'the unconquered Son'! (In the Bible a prophesy about the Jewish savior, who Christians believe is Jesus, is called 'Sun of Righteousness'.)
The Jewish festival of Lights, Hanukkah starts on the 25th of Kislev (the month in the Jewish calendar that occurs at about the same time as December). Hanukkah celebrates when the Jewish people were able to re-dedicate and worship in their Temple, in Jerusalem, again following many years of not being allowed to practice their religion.
Jesus was a Jew, so this could be another reason that helped the early Church choose December the 25th for the date of Christmas!
Christmas had also been celebrated by the early Church on January 6th, when they also celebrated the Epiphany (which means the revelation that Jesus was God's son) and the Baptism of Jesus. Now Epiphany mainly celebrates the visit of the Wise Men to the baby Jesus, but back then it celebrated both things! Jesus's Baptism was originally seen as more important than his birth, as this was when he started his ministry. But soon people wanted a separate day to celebrate his birth.
Most of the world uses the 'Gregorian Calendar' implemented by Pope Gregory XIII in 1582. Before that the 'Roman' or Julian calendar was used (named after Julius Caesar). The Gregorian calendar is more accurate that the Roman calendar which had too many days in a year! When the switch was made 10 days were lost, so that the day that followed the 4th October 1582 was 15th October 1582. In the UK the change of calendars was made in 1752. The day after 2nd September 1752 was 14th September 1752.
Many Orthodox and Coptic Churches still use the Julian calendar and so celebrate Christmas on the 7th January (which is when December 25th would have been on the Julian calendar). And the Armenian Apostolic Church celebrates it on the 6th January! In some part of the UK, January 6th is still called 'Old Christmas' as this would have been the day that Christmas would have celebrated on, if the calendar hadn't been changed. Some people didn't want to use the new calendar as they thought it 'cheated' them out of 11 days!
Christians believe that Jesus is the light of the world, so the early Christians thought that this was the right time to celebrate the birth of Jesus. They also took over some of the customs from the Winter Solstice and gave them Christian meanings, like Holly, Mistletoe and even Christmas Carols!
St Augustine was the person who really started Christmas in the UK by introducing Christianity in the 6th century. He came from countries that used the Roman calendar, so western countries celebrate Christmas on the 25th December. Then people from Britain and Western Europe took Christmas on the 25th December all over the world!
