Unfortunately, we cannot create a horoscope book for you if your exact time of birth is completely unknown. The rising sign, which forms the foundation of the entire chart, changes every two hours, so knowing at least the hour of your birth allows us to proceed. However, for the accuracy of the dates in the "Planetary Periods" chapter, the timing of each subchapter is highly dependent on your exact time of birth. A difference of just 10 minutes can shift the start of a specific subchapter by about a month—earlier with +10 minutes, or later with -10 minutes. Therefore, while the dates of the main Planetary Period may be relatively accurate, the dates for its sub-chapters provided in the book should be considered approximate. If you're unsure of your birth time, we recommend consulting a professional astrology counselor who specializes in rectification.
