How the finder works
It uses the conventional tropical zodiac start dates (Aries from March 21, Taurus from April 20, and so on) and counts a birthday as on a cusp if it falls from three days before to two days after a sign's start date.
Limitations: the Sun's actual entry into a sign moves by about a day from year to year, and depends on time zone, so dates near a boundary are uncertain without your birth year, time, and place. Cusp widths and nicknames are popular conventions, not standards. Astrology is offered here as culture and entertainment; it has no demonstrated predictive power.
