Don't expect astrology to have the same consistency as, say, astronomy - the "cusp" confusion happens because different systems draw the zodiac boundaries on different dates, so April 19th genuinely lands in the gray zone depending on who's calculating it. Whether that matters for your horoscope is really the bigger question: most astrologers would say your cusp placement adds complexity to your chart, but honestly, if predictions aren't matching your actual life, that's probably because astrology works more as a framework for reflection than prediction. Are you looking for something specific the horoscopes should be telling you, or just curious why they keep contradicting each other?
