The early Christians incorporated the pagan celebration of winter solstice to the celebration of the birth of Christ. The solstice normally falls on the 21st of December and is followed by three days where the sun rises in the same place on the horizon. It is on December 25th that movement of the sun can be detected and so begins longer days of light. Thus, we celebrate the birth of Christ on December 25th.
Happy Christmas. May we all enjoy the light.

Merry merry Christmas, Kim. Thank you for telling us the story of how Christmas started – the beginning of light and longer days when Jesus was born. I hope the world gets a lot more light this year instead of darkness and anger and trumpiness.
Merry Christmas, Kate! You are a shinning star ❤️
And that’s why I waited until December 27th to be born. I needed assurance that the end of the world wasn’t near. Go towards the light Alan.
