Pat Shingleton for Monday, Dec. 24, 2012 Pat Shingleton for Monday, Dec. 24, 2012 Advocate story Dec. 24, 2012 Comments Astrophysicist Grant Matthews believes April 17, 6 B.C., is the best date for the appearance of the Christmas star. The wise men were Zoroastrian astrologers who would have calculated the planetary alignment in Aries as a sign that a powerful leader was born. It also could have meant that the leader was destined to die at an appointed time and their gift of myrrh was used for the preservation of a body. Matthews notes one born under the sign of Saturn denoted a powerful leader within the alignment of the sun, Jupiter, the moon and Saturn. Even though the heavenly sign at the birth of Jesus Christ was an unusual alignment, it is impossible to ascertain what caused the light. Fastcast: All is calm; all is bright. Showers.
