Note 3597 — THE JULIAN CALENDAR AND THE CHRONOLOGY OF CAESAR’S INVASIONS OF BRITAIN
Reading edition
The year 702, as we have already seen, contained 378 days; each of the five years 703, 704, 705, 706, and 707 contained 355 days; the year 708 contained 445 days; one of the four years 709, 710, 711, and 712 contained ex hypothesi 366 days, and the other three 365; and if there had been no intercalation in 713, that year would have contained 365 days. Then the number of days from the Kalends of January, 702, to the last day of December, 713, would have been 378 + 355 × 5 + 445 + 366 + 365 × 4 = 4,424 days, which is a multiple of 8.
