Lunar return chart
About every 27 days the Moon comes back to the exact degree it held when you were born. The chart cast for that moment is your lunar return chart, and it is read as the emotional weather of the following four weeks: what will occupy your mind and heart, where you will look for comfort and which area of life will ask for attention.
Look first at the house the Moon falls in and at the rising sign of the return chart; the planets close to the angles show what will stand out that month. Because the Moon moves about half a degree an hour, the lunar return needs an accurate birth time.
The chart is calculated for the lunar return in effect on the date you choose. Like the solar return, it is calculated for the place where you are at the time of the return; if you leave the city field empty, your birthplace is used.
