This program is very useful for astronomically comparing two dates in a simple way, it takes into account the areas of the sky defined by the chinese solar months, you can use two dates of birth (for compatibility) or a birth date and a particular day to see the trends for that person in that time.

This information complements that of the chinese natal chart and the 4 columns of destiny (Ba-Zi), for example the column of the day in the latter is somewhat controversial, because it is calculated based on the other three columns, and formerly it used to be time of conception of the person, also there are those who think that the position of the Moon in the chart above replaces or supplements the sign of the day in Ba-Zi astrology.

Besides, as can be seen, the other major planets (Mercury, Venus, Mars and Saturn) are absent from the previous graph, even if they have always been taken into account in chinese astrology, the only reason for this is that makes things easier to understand for those who are beginning to study chinese astrology.

When I have time I plan to expand this program with more information and options, but for now it will have to do.
