The cardinal signs are a group of zodiac signs in astrology that represent the unique ways each group of signs expresses their energy, reacts to circumstances, and navigates through life. There are four cardinal signs: Aries, Cancer, Libra, and Capricorn. These signs are known as the initiators of the zodiac and correspond with the changing seasons. For example, Aries marks the beginning of spring in the Northern Hemisphere, Cancer marks the beginning of summer, Libra marks the beginning of autumn, and Capricorn marks the beginning of winter. Cardinal signs are known for their innovation, trying new things, and taking action. They are the movers and shakers of the zodiac and are often leaders in their communities. If you are a cardinal sign, you are likely a born leader and initiator who displays a great drive in work as well as in relationships.
