No one knows the real birthday of Jesus. No date is given in the Bible and there is no definitive reason for celebrating His birthday on the 25th December. The early Christians had many arguments as to when it should be celebrated but the first recorded date of Christmas being celebrated on December 25th was in 336, during the time of the Roman Emperor Constantine (he was the first Christian Roman Emperor). A few years later, Pope Julius I officially declared that the birth of Jesus would be celebrated on the 25th December. We have kept the date ever since.
So, it being December 25th today, we wish everyone a merry Christmas and pray for blessings, peace and joy for all. May God guide us through the many evils that surround us in this world and lead us to salvation through His Son, Christ Jesus.
