Robert Tulip wrote:You say the calend "seems to be included." Yes, if the 1855 footnote claiming the 25 December solstice estimate is accurate as indicating Pliny's intention. But a modern footnote alone is a flimsy reed, especially when a more natural reading would put the eighth day at 24 December.
If Pliny had said "the second day before the calends", your logic would put that at 31 December, whereas a normal reading would assume it meant 30 December.
Normal
according to whom? Modern English readers without accurate knowledge of how to read an ancient Latin text?
Pliny the Elder in
Natural History, 18.59, wrote "a. d. VIII kal. Ian."
If Pliny
had written "a. d. II kal. Ian.", then the reader
would logically understand by that what we call 31 December, but Pliny would not likely have written that, because Pliny had good Latin and that day was most properly written as "pr. kal. Ian," abbreviating "pridie kalendas Ianuarias".

"N. B. In English translations of papyri in which a Roman date occurs knowledge of the inclusive counting is presupposed: pro e kalandwn Maiwn = 5 (days) before the calends of May = April 27." [April is a month with 30 days in the Julian calendar.]

"In the Roman system pridie follows immediately the 3rd day before a fixed day. Since pro mias + a fixed point is used for pridie + a fixed point, one should not expect to find pro duo + a fixed point. But there are two papyri which use exactly such a date: P. Cairo Isid. 87,8: pro duo kalandwn Maiwn ... and P. Dura 32, 3-4 [pro] dekaoktw kalandwn Maiwn (= April 30, ed.). These scribes used to the series pro dekaoktw kalandwn Maiwn --- pro triwn kalandwn Maiwn continued with pro duo kalandwn Maiwn which thus became another way of expressing pridie kalandwn Maiwn. P. Cairo Isid. 87, therefore should be dated to April 30, 308 A.D."

"All students of the classical languages are aware that, in referring to intervals of time, the Greeks and Romans often employed a method of reckoning which was inclusive and consequently different from our own. The Greeks, for example, refer to the period between two celebrations of the Olympic games (e.g. 776-772 B.C.) as a pentaethris, though we should call it a four-year interval. One instance of this kind of usage in Latin is the stereotyped formula employed in expressing a date: ante diem quitum Id. Mai. is 11 May, though we should say that there was an interval of four days only between 11 and 15 May. Another instance is the use of tertiana and quartana as applied to fevers which recur on alternate days and on every third day respectively."

"... and the date of that was ante diem sextum kalendas Martias, or, as we call it, February 23." [February has 28 days in the Julian calendar, and as the footnote remarks here, "Caesar, with his usual desire to upset the traditional dating as little as possible, inserted the extra day of the fourth year in the same place, hence the name bissextile for a leap year, i.e., the year in which the date a. d. vi kal. Mart. comes twice. For, our modern almanac makers to the contrary notwithstanding, there is no such day as Feb. 29 in leap-year or out of it; every fourth year February has two 23rd's."]
