Clement of Alexandria  On Daniel 12:11-13

(2nd Century)

"We have still to add to our chronology the following, -- I mean the days which Daniel indicates from the desolation of Jerusalem, the seven years and seven months of the reign of Vespasian. For the two years are added to the seventeen months and eighteen days of Otho, and Galba, and Vitellius; and the result is three years and six months, which is "the half of the week," as Daniel the prophet said. For he said that there were two thousand three hundred days from the time that the abomination of Nero stood in the holy city, till its destruction. For thus the declaration, which is subjoined, shows: "How long shall be the vision, the sacrifice taken away, the abomination of desolation, which is given, and the power and the holy place shall be trodden under foot? And he said to him, Till the evening and morning, two thousand three hundred days, and the holy place shall be taken away."

"These two thousand three hundred days, then, make six years four months, during the half of which Nero held sway, and it was half a week; and for a half, Vespasian with Otho, Galba, and Vitellius reigned. And on this account Daniel says, "Blessed is he that cometh to the thousand three hundred and thirty-five days." For up to these days was war, and after them it ceased. And this number is demonstrated from a subsequent chapter, which is as follows: "And from the time of the change of continuation, and of the giving of the abomination of desolation, there shall be a thousand two hundred and ninety days. Blessed is he that waiteth, and cometh to the thousand three hundred and thirty-five days." " (The Ante-Nicene Fathers, vol. 2, p. 334)
