A note on November 21 birthdays

A cusp day, November 21 holds Scorpio at 28.1 to 30.0 degrees in most years, the sign's final day, but a small slice, about 4 percent of years, catches the first hours of Sagittarius instead, since the sign change falls between November 21 and November 22. In astrological tradition, that closing degree of Scorpio still reads through Pluto as depth and trust, while an early Sagittarius moment favors Jupiter's generosity and room to grow. By this site's points method, Scorpio's best pairing remains Cancer or Pisces at 8 points for a trine.
