A note on February 18 birthdays

This is the cusp between Aquarius and Pisces, with the Sun at 28.5 to 30.0 degrees of Aquarius, its last full day in the sign before Pisces begins on February 19. Astrologers read Uranus, still ruling here, as independence and change, and Neptune, taking over next, as ideals and empathy. Gemini and Libra hold Aquarius' strong match, 8 by this site's points method, and when Pisces opens, Cancer and Scorpio take that same strong place, also 8, for the water sign.
