the well-known Egyptian administrative solar calendar, and presumably the basis for the 13th-century BC Jewish lunar calendar), and (b) the fact that the modern surviving small community of Samaritans did not reveal the calculations underlying their lunar calendar (preserving the Egyptian reckoning) to outsiders until the 1960s. In a review of Humphreys' book, theologian William R Telford points out that the non-astronomical parts of his argument are based on the assumption that the chronologies described in the New Testament are historical and based on eyewitness testimony. In doing so, Telford says, Humphreys has built an argument upon unsound premises which "does violence to the nature of the biblical texts, whose mixture of fact and fiction, tradition and redaction, history and myth all make the rigid application of the scientific tool of astronomy to their putative data a misconstrued enterprise." As Telford had pointed out in his own book in 1980, "the initial three-day structure found in [Mark 11] is occasioned by the purely redactional linkage of the extraneous fig-tree story with the triumphal entry and cleansing of the temple traditions, and is not a chronology upon which one can base any historical reconstructions." Resurrection "on the third day" The Gospels do not describe the resurrection, but report the discovery of Jesus' empty tomb "very early on the first day of the week" (Mark 16:2), and subsequent appearances of Jesus. A potential chronological contradiction arises in the fact that the resurrection is referred to as happening "on the third day" (e.g. Matt 16:21) whereas elsewhere Matthew (Matt 12:40) states that Jesus would be buried "three days and three nights". The modern concept of zero as a number was introduced by Indian scholars only in the fifth century AD, so that for example the currently used Gregorian calendar does not have a "year 0" and instead begins with the year AD 1 which is immediately preceded by 1 BC. Applied to the reckoning of days, in the absence of a day "zero", that is, using inclusive counting, many modern languages (e.g. Greek, Italian, Spanish, French, Portuguese, Welsh) continue referring to two weeks as "fifteen days", whereas in English, which does observe zero and thus uses exclusive counting, this space of time is referred to as a fortnight. Following general practice at the time, the Gospels employ inclusive counting, highlighted in Mt 27.62–64: where Matthew uses "after three days" and "until the third
