The characteristic features are the elaboration of a five-yearly luni-solar cycle comprising 1830 civil days, 1835 sidereal days, 1800 solar days, 62 synodic months, 5 solar revolutions and 67 lunar revolutions. According to the system taught in these two works, the year-length works out to 366 days and the synodic month to 29 1/6 days.
