Tonight is the night that Jesus and Ibrahim (PBUT) were born

Christian have and will continue to celebrate Jesus the Christ's birth on the 25th of December (Unless they are Jehovah's Witness). This is not of course when he was actually born as most historical consensus says late summer early fall.

But that does not change the fact that it still would be celebrated by Christians in December, unless you are talking about another Jesus.

I am a Christian and not a JW , I and my family dont celebrate Christs birthday at Christmas, we do celebrate on December 25 whatever our family are celebrating. They are not Christians and dont believe in Christ and celebrate something to.
Probably something pagan, who knows, who cares. Its a good family day.
