c13.31

In the old cycle of 8 years the lunar months consisted nominally of 30 days each, one day being "omitted between the 20th and 30th of every alternate month. But in those months from which a day was deducted, the last day was still called τριακὰς, and the day omitted was perhaps the 29th, or any other day but the 30th."† Meton also retained the nominal value of the month at 30 days, but he proposed a new scheme for the days to be omitted. As 235 lunations at 30 days each amounted to 7050 days, or 110 days in excess of the 6940 days assigned to 19 solar years, he devised the cumbrous and inconvenient plan of omitting every 63rd day throughout the cycle; but it is not known whether he included or excluded the seven intercalary months. These omitted days, or ἡμέραι, ἐξαιρέσιμοι, are shown in the table, which is altered from Clinton's Attic tables to suit the Macedonian Calendar.
