Mercury retrograde is a key event in astrology. When Mercury, the planet of intellect, speech, commerce, and communication, is retrograde (appears to move backward), it can bring both benefits and challenges to certain zodiac signs. Currently, on July 18, 2025, Mercury has gone retrograde in Cancer. This retrograde will last until August 11, 2025. Due to this transit, four zodiac signs will receive Raja Yoga for the next 70 days. Let's explore these signs in detail in this post.
