In traditional astrology, the signs are labels for 12 even slices of the ecliptic, so each sign equals 30° and there is no strict correspondance between the signs and the actual positions of the constellation they are name after.
Western astrology fixes the beginning of Aries at the Spring equinox which was the case when the system was created 2000 years ago, but since then the equinox has progressed so that constellation of Aries is no longer at this position.
Eastern astrology still places Aries at its original position so that it is not at the Spring equinox.
Traditionally, signs are markers of time, both for the seasons with the sun sign, and for day time for the rising sign.
