Was Jesus born on June 17?

The birthdate of Jesus is not knowable. Attempts to ascertain the year and the month have been made, trying to accommodate the Biblical account with any unusual astronomical events about that time. But these ignore the fact that the Nativity story, with its Magi following a mysterious Star in the East, was borrowed from the older myth of Mithras, the Zoroastrian God of the Word, whose miraculous birth was celebrated on December 25.
