human skeleton wiki:
an skeleton is made of bones, some of them joined together, supported and supplemented by a structure of ligaments, tendons, muscles, and cartilage.The skeleton changes composition over a lifespan. Early in gestation, a fetus has no hard skeleton â bones form gradually during nine months in the womb. When a baby is born it has more bones than it will as an adult. On average, an adult human has 206 bones in their skeleton (the number can vary slightly from individual to individual), but a baby is born with approximately 270. The difference comes from a number of small bones that fuse together during growth. These include the bones in the skull and the spine. The sacrum (the bone at the base of the spine) consists of six bones which are separated at birth but fuse together into a solid structure in later years.

Christmas wiki:
[mas (literally, the Mass of Christ) is a holiday in the Christian calendar, usually observed on December 25, which celebrates the birth of Jesus. According to the Christian gospels, Jesus was born to Mary in Bethlehem, where she and her husband Joseph had traveled to register in the Roman census. Christ's birth, or nativity, was to fulfill the prophecies of Judaism that a messiah would come, from the house of David, to redeem the world from sin. Early Christians celebrated more the subsequent Epiphany, when the baby Jesus was visited by the Magi (and this is still a primary time for celebration in Spain). Efforts to assign a date for his birth, though better known from Writings from some centuries later, would have been important to all Christians then, no less than now. The precise chronology of Jesus' birth and death as well as the historicity of Jesus are still debated.
