Samuel's 40 Year Reign Ended; Saul Began 40 Year Reign—Acts 13:21

Q: WHAT YEAR DID SAMUEL CEASE TO BE JUDGE OF ISRAEL?

On the Hebrew calendar, sometimes called the biblical calendar, the year was 3008 AM.
Acts 13:21 New King James Version (NKJV)
21 And afterward they asked for a king; so God gave them Saul the son of Kish, a man of the tribe of Benjamin, for forty years.
