What’s Observed on July 10

Born on July 10: Cancer ♋
Cancer, the fourth sign of the zodiac, spans June 21 to July 22 and is symbolized by the crab, an animal known for carrying a protective shell while remaining soft and vulnerable underneath. Ruled by the Moon, the celestial body long associated with emotion, intuition, and the subconscious, Cancer is widely regarded as one of the most nurturing and emotionally attuned signs of the zodiac. As a Water sign, Cancer navigates the world through deep feeling, often forming strong emotional bonds and an acute sensitivity to the moods of others. Its Cardinal modality places it at the start of summer, beginning right at the June solstice, reflecting an instinct to initiate and create, especially around home and family. People born under this sign tend to be deeply loyal, protective of loved ones, and drawn to creating a comfortable, secure home environment. Cancer's emotional depth is a genuine strength, but it can also make the sign prone to moodiness or withdrawal when hurt, retreating like a crab into its shell until it feels safe enough to re-emerge.
