The long-period calendar moon-solar cycles

Abstract

The paper is devoted to improvement of the real (tropical) moon-solar cycle. Calendar long-period moon-solar cycles (Julian and Gregorian), which use for the calculation of age of the Moon the Julian and Gregorian calendar years instead of tropical year, as in the real moon-solar cycle, are introduced. It allows to increase the accuracy of a calculation of the age of Moon at very large time interval.
