Lunar return calculator
About every 27.3 days the Moon comes back to the exact place it held when you were born. A chart cast for that moment, the lunar return, sets the emotional tone and the main concerns of the month ahead. It is cast for the place where you are living now.
About lunar returns
Lunar returns are the monthly counterpart of the solar return. Because the Moon moves about 13° a day, the return time shifts by a day or two each month, and the return Ascendant changes sign almost every month, giving each month its own character. The method here uses the tropical zodiac and whole-sign houses from the return Ascendant, as in the Thai edition.
