Due to a phenomenon called precession of the equinoxes (where the Earth's axis slowly rotates like a spinning top in a 25,700-year cycle), there is a slow shift in the correspondence between Earth's seasons (and calendar) and the constellations of the zodiac.
Newspapers often print astrology columns which purport to provide guidance on what might occur in a day in relation to the sign of the zodiac that included the sun when the person was born.
