June 20 Zodiac Sign

Tradition: Western astrology. A tradition, not a forecast. Astrologers read it this way; the evidence does not.

By Suraj Giri

June 20 is Gemini on the dates most calendars use, but it is a boundary day: from 1950 to 2029, about 98 percent of June 20 birth hours in US Eastern time fell in Gemini and about 2 percent in Cancer.

A note on June 20 birthdays

June 20 sits on the cusp between Gemini and Cancer, holding the sign's final degrees, 28.0 to 30.0, while a sliver of Cancer, just 0.0 to 0.3 degrees, already reaches in. Some years tip the Sun's crossing later, letting that trace of the crab's water show early. Gemini's warmest pairings, Libra and Aquarius, still take the sign to 8, a trine and its top rating under this site's points method. Cancer waits just ahead, ruled by the Moon and read as needing safety first.
