The timing of the crucifixion and resurrection

Saint Matthew says that he was crucified at the sixth hour; indeed, the saint has studied the darkness that follows from the sixth hour. He is therefore crucified at the preparation hour at the third hour, and one day was reckoned to him from the third hour until the ninth. For after the crucifixion, the remainder of the work of salvation for those under the earth was being accomplished; from the sixth to the ninth is one night, and from the ninth to evening is one day.

Thus, there have been three days and two nights. Through the whole Sabbath is one day, and the night that breaks into Sunday. What was spoken concerning him was fulfilled: 'it is necessary that the Son of Man be done in the heart of the earth three days and three nights.' He was crucified at the third hour, in the fullness, on the fourteenth Sabbath according to the moon, on the twentieth of the month of Phamenoth, before the thirteenth kalends of April. For this reason, we fast also on the preparation day.

But he rose on the day of Sunday, when the roosters crowed, during the night of the equinox coinciding with the equinox, namely on the twentieth of the month of Phamenoth, which is interpreted as Nisan among the Hebrews. The months of the Hebrews precede the months of the Egyptians, and the months of the prosperous Athenians likewise precede those of the Lacedaemonians by eight days, if such is the case. The night possessed the same hours, and the passing day possessed the same hours.
