After Christ began his official ministry, how long did He minister before He entered into His Galilean ministry? I am following Robertson's "Harmony", but cannot figure out how many months passed between Christ's baptism through His meeting with the Samaritan woman.

After this meeting, His Galilean minstry begins. Does anyone have an estimate of the durstion of our Lord's ministry from His baptism through His meeting with the Samaritan woman? Thanks.
"In Christ",
Bobby

"Every minister in those days had a V.D.M. degree: Verbum Dei Minister. When, therefore, I became a teacher of apologetics it was natural for me to think, not only of my Th.M. and my Ph.D., but above all of my V.D.M. The former degrees were but means whereby I might be true to the latter degree." Cornelius Van Til
