What zodiac sign is June 12?
June 12 falls in Gemini, which runs from May 21 to June 20 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 12 a cusp birthday?
Not by the usual definition, which counts the first and last couple of days of a sign. June 12 is day 23 of Gemini season, so it is normally read as a clear Gemini birthday.
Which decan is June 12?
June 12 is in the third decan of Gemini (June 10–20). In the traditional Chaldean system this decan is ruled by Sun, which astrologers say adds its own flavour to Gemini. 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.
