If you go back historically, look at the data available. The current system has Christ's birth as December 25. During the Roman conquest of Brittan, the Pagans were celebrating Yule around the 21st. This was having a problem with converts. Why should the Pagans stop their drunken holidays to become Christians? The answer was for Rome to move the birth date of Christ from the middle of the year to where we celebrate it now. This way, the Pagans would convert easier. This does cause an eyebrow raise among some. I am not against Christianity, just for information. By the star leading them, it is accepted that the magi were rulers in their own rite. Being a Roman occupied province, it was customary to 'check in' with the local authorities. Herod wanted to find this "King of the Jews" so that he could take him out before the threat became too big.
