Nissan 1 means a new beginning. Jesus was born in the Spring on March 20, 6BC. There is one time of the year when shepherds are out with their sheep, and that’s in the Springtime. Jesus was the Lamb of God. He was born in Bethlehem. Bethlehem was the place where the sacrificial lambs are born. Jesus was the Passover Lamb. He dies on Passover and is born around the same time that he died. God fulfills his holy days. Nissan 1 is the real New Year. The old calendar is replaced by the new calendar. When Jesus was born, there was a new calendar put in place. Jesus died during the Passover with a full moon. He was born on the New Moon of the time of Nissan 1.
