Your sun sign is often the first part of astrology you encounter. In traditional practice, a birth chart explores a wider set of symbols, arranged around the date, time and location of birth.
You do not need to learn everything at once. Start by noting the questions you want to explore, and make sure you have the most accurate birth details available to you. If the time is uncertain, tell your guide rather than guessing.
Treat a reading as a starting point for reflection, not a fixed prediction. Your circumstances, choices and conversations matter more than a label.
