Jesus probably was born in October when sheeps were taken out for grazing(according to Bible) and palm dates ripen so Mary could feed herself and to breast feed baby Jesus(according to Quran).But the christmas is celebrated on 25th December because this was the Roman pagan festival of Sun god and after ascension of Jesus Jews did everything to destroy name,teachings and book of Jesus and we see them 100% successful.Celebrate christmas on 25th December is in this aim not according to Jesus.

Jesus commanded that we commemorate his death, not his birth.—Luke 22:19, 20. Jesus’ apostles and early disciples did not celebrate Christmas. The New Catholic Encyclopedia says that “the Nativity feast was instituted no earlier than 243 [C.E.],” more than a century after the last of the apostles died. There is no proof that Jesus was born on December 25; his birth date is not recorded in the Bible. Christmas is not approved by God because it is rooted in pagan customs and rites2 Coran6:17
