The seven intercalary months of the Metonic cycle were added at the end of the 3rd, 5th, 8th, 11th, 13th, 16th, and 19th years. But in the Macedonian Calendar the embolismic month was placed in the middle of the year immediately preceding Xanthikos.‡ Clinton supposes that the embolismic months were also subject to the retrenchment of the 63rd day, should it happen to fall upon them. But this cannot have been the case, otherwise the number of omitted days would have amounted to 111·9, or nearly 2 in excess of the required number of 110. Meton’s scheme consisted of a cycle of 19 years, each of 12 months of 30 days, with seven intercalary months also of 30 days, making altogether 7050 days, from which 110 days were to be deducted to obtain the required number of 6940 days, by omitting every 63rd day. Now if the embolismic months had been subject to curtailment, the number of omitted days would have been 112. But if they were not subject to these omissions, the required number of 6940 days would have been obtained by passing them over, and striking out the day from the following month. This arrangement is shown in Table VII, where the embolismic month of 30 days is placed in the middle of the year between Dustros and Xanthikus.
