1st decan of Cancer: Venus

Venus softens the sign's edges and makes relationships, taste and pleasure more central to how these people move through life.

What zodiac sign is June 30?
June 30 falls in Cancer, which runs from June 21 to July 22 in the tropical zodiac. The Sun changes sign at a slightly different moment each year, so the boundary can fall a day or so either side of these dates. If you were born close to the edge, your birth year, time and place decide it.
Is June 30 a cusp birthday?
Not by the usual definition, which counts the first and last couple of days of a sign. June 30 is day 10 of Cancer season, so it is normally read as a clear Cancer birthday.
Which decan is June 30?
June 30 is in the first decan of Cancer (June 21–30). In the traditional Chaldean system this decan is ruled by Venus, which astrologers say adds its own flavour to Cancer. Some modern astrologers assign decan rulers by element instead, which gives different planets, and decans are strictly 10° slices of the zodiac, so the date range is approximate.
What are the birthstone and flower for June?
The modern birthstone for June is Pearl and the birth flower is the rose. These come from calendar tradition rather than astrology, and the lists vary by country and source.
