The Hebrew calendar is luni-solar, as are the Chinese and Hindu, and old Roman Calendar. Months are the intervals between observations of a new (waxing crescent) moons. Occasionally, and extra month is added since there are very nearly exactly 235 lunar cycles in 19 solar years. 19 x 12 = 218, leaving seven “leap months” (technically intercalary months) per 19 years. The extra months are added to keep the names of the months in sync with the seasons.
Mars and earth have never been in orbital resonance, much less synchrony. Neptune and Pluto are in 2:3 orbital resonance and there is a strict orbital resonance among three of Jupiter’s Galilean Moons.
