The twelve signs
A sign is a thirty-degree slice of the ecliptic, not a personality. What it does is colour whatever planet is standing in it, so each of these says how that slice behaves, and leaves the fortune-telling to the readings.
Dates shift by a day either way from year to year, because the Sun doesn't keep to the calendar. If you were born near a boundary, cast the chart , it's free, and it settles the question exactly.

A sign says how. The planets say what, and the houses say where.
Your own
Reading about Scorpio is not the same as finding out you have four planets in it. Cast a chart. It costs nothing.
The other system
Twelve animals rather than twelve constellations, and a year that turns in February. The Chinese zodiac.
