- In the 15th year of Tiberius (Aug. 28AD to Aug. 29AD), John the Baptist began his public ministry (summer of 28AD).
- At that time Jesus was "about thirty years old", which statement would be precisely true if Jesus were born in 3BC. (Luke 3:23) a. The gospel of John records three Passovers during Jesus' ministry. The first when Jesus was 30½ years old (John 2:13), a second when He was 31½ years old (John 6:4) and His last when He was arrested and killed. (John 13:1) So, we see that His ministry lasted about 2½ years and He died at the age of 32½ years.
