How many years were between Pentecost and the stoning of Stephen?
Between Pentecost in 29 A.D. and the stoning of Stephen, there was a seven-year interval. This places Stephen's stoning in 36 A.D., during Saul's intense persecution of Jewish believers before Saul's conversion on the road to Damascus the next year.
Les explains that Christ was crucified and Pentecost took place in 29 A.D. He feels there was a seven-year interval between Pentecost and the stoning of Stephen, which would be in 36 A.D. This occurred when Saul was at the height of his persecuting those Jewish believers and had brought about the stoning of Stephen. The next year, Saul's conversion on the road to Damascus would take you up to 40 A.D. when he went to Cilicia. Les notes that all during the book of Acts, time is moving on; it isn't all happening in just a year or so.
