According to the tropical astrology, the Sun stays in the Aquarius zodiac sign from January 20 to February 18. All people born in any of these 30 days are considered to be in the Aquarius zodiac sign.

We all know that each of the twelve zodiac signs comes with its own set of characteristics and symbols. Although you might expect all people born in the same zodiac sign to be alike it seems that they are just as diverse as any other group of people. However, this is not a reason to doubt the meanings of the zodiac. The explanation of this diversity stays in the personal birth charts, in the cusps and decans of each zodiac sign.

As for the birth charts these represent the astrological map of the planets at the time of birth of an individual and reveal a personalized reading. We will discuss about birth charts in another article.

A decan of a zodiac sign is one of the third periods that sign is divided into. Each decan has its own planetary ruler which influences the basic characteristic of that zodiac sign.

A cusp refers to an imaginary line drawn in the zodiac between two zodiac signs. It also refers to the 2-3 days that are at the beginning and at the end of each zodiac sign and are said to also be influenced by the neighbor zodiac sign.
