Why do Christians celebrate Christmas on December 25—or January 6—or even September 11? Are these dates rooted in pagan traditions, theological patterns, or something else entirely? In this episode of Wise Counsel, we explore how God redeems time, how early Christians thought theologically about calendars, and how biblical scholarship, including the work of Dr. Michael Heiser, brings deeper insight into the real birthday of Jesus—and what it all means for living with gospel-centered purpose.
