Like all things astrology, there are a few different interpretations of exactly what being born on the cusp means. Some say it only applies to those born at the exact moment the sun is transitioning from one sign to the next. However, most astrologers favor the theory that cusp signs apply to those born just before or after the transition from one sun sign to the next. For instance, the last day of Gemini is June 20 and the first day of Cancer is July 21; the Gemini/Cancer cusp is June 17-23. If you were born on June 20, you’re a Gemini but you are also on the cusp, so your horoscope is also influenced by Cancer. The effect is stronger during the last days of the sign, so Geminis will be more influenced by Cancer than Cancers will be by Gemini at the beginning of their sign.
