Planetary Returns are based on the idea that a planet’s return to its natal position creates a valid chart describing a period of time.  The most common of these, of course, are Solar and Lunar Returns.  It is important to distinguish between tropical returns and sidereal returns.  The former uses the ever-shifting tropical zodiac, based on the vernal point as its frame of reference.  The sidereal zodiac uses the “fixed” backdrop of the stars.  In usage, it’s important to realize that these types of charts are read differently.  The tropical solar return is a normal chart that is read in pretty much the “standard” way.  The sidereal solar/lunar returns however, use angularity and partile aspects as interpretational points.  A recurring issue/question with returns is whether we use the birthplace, residence, or current location in calculating the charts.    Research continuously points to the residence as being the correct answer, though when the person has spent a considerable amount of time at another location (for instance relative to some event), then often it is the relocated chart that appears to be more on point. We aren’t limited to just solar and lunar returns.  Any planet can produce a return chart… Mars return, Jupiter return, Saturn return, etc.  It is to note that (for instance) a solar return relates to a year of time, since it returns to its position once each year.  A lunar return relates to a (lunar) month of time, since it returns to its position once every month.  A Saturn return, since it close to 30 years in the making, rules a similarly long period of time.  Note the Solar Return to Moon and Lunar Return to Sun charts, as they are performing at least as well as normal returns and are presented/explained in another section.
