FINAL REMARKS
This rather technical study enabled us to substantiate the temporal landmarks of Jesus's life.
It has become easy, from the Gospel according to John, to draw up a precise chronology of his public life between 34 and 36.
It enables the researcher to broaden the discussion to other matters.
The fact that the Gospels are historically rigorous and their inner coherence is a token of their veracity and thus a sound support of faith.
Flavius Josephus has published The Jewish War 9 years after the facts, at the latest, therefore it is not improbable to date the first evangelical text - that of Matthew, according to ancient authors - around 45 AD. An event is not legally borne out until two testimonies tally. Thus we can reasonably think that John, the other eyewitness, must have written his own record of the facts around the same time.
The three Wise Men visiting the newborn Jesus in July is compatible with a theological intuition developped by Sylvie Chabert d'Hyères, according to whom the annunciation would have happened on Yom Kippur (Tishri, 10th), i.e. on September, 22nd, -5 (6 BC) and the birth around the summer solstice.
