When did the transfiguration occur?

What follows is one scholar’s way of reading this disagreement — a critical-historical view that often concludes the texts genuinely disagree. It draws on the peer-reviewed sources listed below and stands as one position among the answers above, presented for transparency, not as GEBible’s position.

This is the slightest of the divergences in the cluster and the one most cleanly resolved by ancient counting conventions. Matthew 17:1 and Mark 9:2 agree precisely: the transfiguration occurred *meta hēmeras hex*, "after six days," following the kingdom-saying. Luke 9:28 reports it *egeneto... hōsei hēmerai oktō*, "it came to pass about eight days after these sayings." The numbers differ by two; the saying and the event are otherwise identical across all three accounts. The manuscript tradition is stable — there is no significant variant turning Luke's eight into six or vice versa — so the divergence is original to the texts, not a scribal slip.

The harmonization (Marshall, Bock, Carson, Geisler-Howe) rests on two solid philological observations. First, the qualifier *hōsei* ("about, approximately") explicitly flags Luke's figure as a round estimate rather than a precise interval. An approximation of "about eight" is not in arithmetic conflict with a precise "six" if the counting bases differ. Second, and decisively, Greco-Roman authors frequently counted inclusively, reckoning both terminal days within a span. On an inclusive count, one brackets the day of the saying and the day of the transfiguration around the six full days that fall between them: 1 (the saying) + 6 (intervening) + 1 (the event) yields the "about eight" Luke gives, while Matthew and Mark count only the six intervening days exclusively. Luke elsewhere shows a tendency toward inclusive reckoning — most familiarly in the "third day" resurrection schema, where a Friday-evening burial to a Sunday-morning rising is counted as three days by including both endpoints. The same author who counts Friday-to-Sunday as "three days" can readily count a six-day gap as "about eight."

A second possibility, raised by Fitzmyer, is that Luke rounded toward the number eight for theological reasons: the eighth day carried resonances in early Christianity as the day of new creation and resurrection (cf. the later patristic ogdoad symbolism, and Luke's own interest in eight-day intervals, e.g. the circumcision and naming sequences in Luke 1-2). On this reading Luke is not contradicting the six-day figure so much as gently restating it within a numerically suggestive frame, with *hōsei* signaling that precision is not the point. Bovon canvasses both the inclusive-counting and the theological-rounding explanations without finding them mutually exclusive.

Critical scholarship is therefore not exercised by this case. Fitzmyer, Bovon, and Marcus treat the divergence as a function of counting convention and Lukan stylistic preference rather than as a substantive disagreement about chronology. There is no competing tradition claiming the transfiguration happened on some materially different occasion; all three Gospels place it at the same point in the narrative, the same number of days after the same saying, with only the counting base differing. This is the kind of item that an honest critical reading should classify as a defensible harmonization rather than a genuine contradiction, since the inclusive/exclusive distinction is a real and well-documented feature of Hellenistic Greek and Luke demonstrably employs it elsewhere. The surface arithmetic differs; the underlying claim does not.

Where the critical reading lands: harmonizable — a counting-convention artifact, not a contradiction.
