The main issue on which the gospel accounts disagree on the order of events is in relation to the denials of Peter by Jesus, which come earlier in Luke’s gospel, and are spread out in John’s gospel. Although his proposals about the different calendars in use at the time of Jesus are speculative (even if plausible), there can be no doubt that different calendars were in use, and that it is quite likely that different gospel writers are making reference to different calendar schedules which could give rise to apparent anomalies in the gospel chronologies.
