If you haven't already, I highly suggest reading the blog post I have up titled "What is a lunar return?" This will give you a good overview of what the lunar return is.

To quickly recap, however, the lunar return is a chart that is cast for the exact moment the moon returns to the degree and time where it was when you were born. I use the current location but others may use the location of birth. Similar to a solar return, this forecast chart gives us an idea of where your heart and mind will be focused. Instead of covering a year, it covers one full moon cycle. It's a useful tool for checking in on the month ahead and understanding where to focus your intention.
