Note 72 — Chapter XXIII · THE DIARY.
Reading edition
For convenience’ sake I have translated the dates of the Attic year which Callias, of course, used with the corresponding days in our reckoning. October 27 would be the “fifth day of the middle of Boedromia.” Each month was divided into three portions, often days each, respectively called beginning, middle, and ending. The days of the last were reckoned backwards. If this month had twenty-nine days only, the third division had nine.
