Over 2000 years, the calendrical difference of 0.0075 d/yr adds up to 15 days. In 1582, a correction of 10 days was done because the original agreement for the date of Easter was made not on AD1 but in AD325 at the Council of Nicea, so the accumulation over 1257 years was 9.4 days. I'm not certain why they dropped 10 days instead of 9; possibly because 1600 would not be a Gregorian leap year? Or possibly because the most prevalent date was already pretty much set by around AD200? -- Mike Dworetsky (Remove pants sp*mbl*ck to reply)

Clearly according to the Synoptic Gospels, but some interpret John to say that Passover that year was on a Saturday. From an Orthodox site: "According to the Gospel of John, Pascha just happened to fall on a Saturdayâ the year that Jesus was crucified. It is important to note that Christ died on the Cross at the very hour the paschal lambs were being slaughtered for the Feast; thus Christ is our Pascha, our Passover Lamb, sacrificed for us." The footnote is to John 11:55. http://www.antiochian.org/node/17394 The chronological table in the Jerusalem Bible dates Jesus' death to 30 A.D. on the basis that it was on a Friday, "the eve of the Passover". -- Jerry Friedman |
