People born on the seventh day of any month are ruled, in numerology, by the number seven. Astrologically, they’re linked to the seventh planet, Neptune, which presides over visions, dreams and psychic phenomena. Those who are ruled by these aspects should pay special attention to staying grounded. A tendency to get caught up in dreams – the unrealistic kind – can be prevalent in their nature. Famous sevens born on this day include Liam Neeson, Prince, Anna Kournikova, Bear Grylls and Dave Navarro.
