Return: A Solar Return is an exact moment when the Sun
returns precisely to birth position after completing a full orbit
through the zodiac. Almost always the date that the Sun returns
to its natal position is the same day as the birthday, or one
day earlier, or one day later. In very rare circumstances, it
could occur 2 days earlier later.
Lunar Return is based on the Moon’s return to its natal position about
once a month (approximately every 27 1/2 days). A chart calculated
for the time the Moon returns to its natal position is the Lunar
Return chart and it gives indications for the coming month.
