What zodiac sign is April 9?
April 9 falls in Aries, which runs from March 21 to April 19 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 April 9 a cusp birthday?
Not by the usual definition, which counts the first and last couple of days of a sign. April 9 is day 20 of Aries season, so it is normally read as a clear Aries birthday.
Which decan is April 9?
April 9 is in the second decan of Aries (March 31 – April 9). In the traditional Chaldean system this decan is ruled by Sun, which astrologers say adds its own flavour to Aries. 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 April?
The modern birthstone for April is Diamond and the birth flower is the sweet pea. These come from calendar tradition rather than astrology, and the lists vary by country and source.
