A note on March 20 birthdays

A cusp date, March 20 splits 56 percent Pisces and 44 percent Aries. The Pisces share runs the sign's last stretch, 28.8 to 30.0 degrees, day 30 of 30, while the Aries share sits at 0.0 to 1.1 degrees, the day before Aries' first day on most calendars, because the exact equinox moment can fall on March 19, March 20 or March 21 depending on the year. In astrological tradition, Pisces favors feeling, empathy and noticing how a room is going, being a water sign, while Aries favors warmth shown openly and drive, being a fire sign that starts things.
