I use this calendar in conjunction with "Astrology for the Millions." (AFTM) As a non-astrologer, it's a quick lookup for interpretations. I keep journal notations in the datebook. One day, I was catching up with my entries. I was astonished to see on the very days I had noted, "very sick today," or "vacation starts," the interpretations (on the aspects in relation to my birth chart in AFTM) had said: illness and poor health indicated; travel very likely. I made a note of these aspects so I can watch out for them next time!
