Portrait of W. Sanday W. Sanday,  The Criticism of the Fourth Gospel

“ But according to the Synoptics this Thursday would be Nisan 14, though on the Jewish reckoning (which counted the days from sunset to sunset) the Last Supper would fall on the beginning of Nisan 15. The Supper itself would be the regular passover, and the Crucifixion will have taken place after the passover. According to St. John we are expressly told that the Last Supper was held ‘before the passover’ (xiii. 1) , on what we should call the evening of Nisan 13, and the Jews the beginning of Nisan 14 ”

George Nichols Packer,  Our Calendar

“ The primitive Christians, in celebrating this anniversary, fell into two different systems.

The Asiatics, on the other hand, following the Jewish calendar, adopted the 14th of Nisan upon which to commemorate the crucifixion, and observed the festival of Easter on the third day following, upon whatever day of the week that might fall, hence they obtained the name of Quartodecimans, (from quarto, four, and decem, ten,) the [Pg 83] fourteenth day men. ”
