Your Planetary Transits
Transits of Natal Moon
Transits involving the Moon are of three kinds: (i) a world (a.k.a. mundane) transit of the Moon with another planet, (ii) the Moon transiting a planet (including the Moon) in the natal chart and (iii) a planet (including the Moon) transiting the Moon in the natal chart. The Moon takes on average 27.32 days to travel 360° along the ecliptic, and thus on average it moves over 13° each day. Because of this high rate of change of ecliptic longitude (compared to the other planets — the next fastest, Mercury, never moves more than 3° in a day) this software can only handle transits of type (iii), in which some planet (possibly the Moon) is transiting the natal Moon.
As an example of such a transit, here is a screenshot showing the transit table for the 6°-square made by Pluto transiting C.G.Jung's natal Moon during July 1945 to October 1951 (years following his heart attack and near-death experience in February 1944, in which he worked on his last book, the alchemical Mysterium Coniunctionis):
These dates can be understood better by comparison with the following transit graphic displayed by the Planetary Aspects and Transits software:
Using the tropical zodiac there are three occasions at which Pluto is exactly square to Jung's natal Moon (the transit table above tells us that these were 1948-08-30, 1949-02-09 and 1949-07-08); these occasions are shown by the red dots intersecting the vertical axis in the transit graph. Using the sidereal zodiac (gray dots) there are, not three, but five such occasions. This again illustrates (as explained here) that the dates of personal transits depend on the zodiac used.
