Paul L. Maier "The Date of the Nativity and Chronology of Jesus" in Chronos, kairos, Christos: nativity and chronological studies by Jerry Vardaman, Edwin M. Yamauchi 1989 ISBN0-931464-50-1 pages 113-129
Eerdmans Dictionary of the Bible states that Jesus began his ministry "ca 28 AD" at "ca age 31". In Chronos, kairos, Christos: Paul L. Maier specifically states that he considers the Temple visit date in John at "around 29 AD/CE", using various factors that he summarizes in a chronology table. Maier's table considers 28 AD/CE to be roughly the 32nd birthday of Jesus, and at http://www.mtio.com/articles/aissar30.htmArchived 2008년 7월 4일 - 웨이백 머신 Paul Meir clearly states that 5 BC was the year of birth of Jesus. Paul N. Anderson dates the temple incident at "around 26-27 AD/CE" Jerry Knoblet estimates the date as around AD 27 AD/CE. In their book, Robert Fortna & Thatcher estimate the date at around AD/CE 28. Köstenberger & Kellum (page 140) make the same statement as Maier, namely that the 32nd birthday of Jesus was around 28 AD/CE when his ministry began.
