No, the zodiac dates have changed due to the progression of the equinoxes.
The belt of constellations through which all the planets move is called zodiac. The true shape of the planetary orbits was discovered by Kepler.

Horoscopes are based on the zodiac, which is connected to a person's birthday. Planets interact within the zodiac and those planets' temperaments are associated with people whose birthdays fall within each range.
Of course you can draw it on paper and it will stay there. But then it won't reflect the real sky; planets change from one constellation to another, sometimes within weeks or so.
yes, they do. The planets wander through the constellations of the zodiac, as do the moon and sun. They all travel on a very narrow path of sky called the Ecliptic - and the constellations along the ecliptic are the constellations of the zodiac. Zodiac is a Greek word that means "ring of animals".
Vedic astrology uses primarily the sidereal zodiac (in which stars are considered to be the fixed background against which the motion of the planets is measured), whereas most Western astrology uses the tropical zodiac (the motion of the planets is measured against the position of the Sun on the Spring equinox). This difference becomes only noticeable over time, after the course of several centuries, as a result of the precession of the equinoxes. Synchronically, the two systems are identical, with just a shift of the origin of the ecliptic longitude by about 22 degrees or days, resulting on the placement of planets in the previous sign in Western charts about 80% of the time. See the related link.
This is called the "Zodiac".
Zodiac signs do not change. People change, many people of all birth dates are willing to change for their loved ones.
Planets, Moon and Sun. The Zodiac, the 12 signs listed in a horoscope, is closely tied to how the Earth moves through the heavens.
The zodiac is an imaginary line through the sky, passing through a number of constellations and close to which the sun, moon and planets can always be found.
No. Your Zodiac sign is determined by the time (minute, hour, day, month, year) and the place (latitude & longitude) of your birth. (If you're wondering if your Zodiac sign has now changed - since the rumor in January 2011 that you'd be changing Zodiac signs - see the Related question.)
If the zodiac never existed I suspect another method would be used to interpret how the movement of the Sun, Moon and planets affect people and events on Earth.
