27⅓, days, so that on an average 13.363 keunòngs occur in the course of the solar year, or in other words, most solar years contain 13, some 14 keunòngs. The interval separating the keunòng from the preceding new moon is greatest in the first month of our solar year. In the course of the following months this interval decreases constantly by two or three days at a time, since the actual lunar month (from one new moon to the next) is always 2 to 3 days (29.5302–27.3333) longer than the period which elapses between two keunòngs. In November the difference is smallest; in other words the keunòng almost coincides with the new moon, while the following keunòng just precedes it, so that the difference is then a minus quantity.
The keunòngs and their lunar dates to 1892 and 1893.We append a table showing the dates of the keunòngs occurring in the years 1892 and 1893, with the interval between each of these keunòngs and the new moon that preceded it.
