What zodiac sign is September 1?
September 1 falls in Virgo, which runs from August 23 to September 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 September 1 a cusp birthday?
Not by the usual definition, which counts the first and last couple of days of a sign. September 1 is day 10 of Virgo season, so it is normally read as a clear Virgo birthday.
Which decan is September 1?
September 1 is in the first decan of Virgo (August 23 – September 1). In the traditional Chaldean system this decan is ruled by Sun, which astrologers say adds its own flavour to Virgo. 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 September?
The modern birthstone for September is Sapphire and the birth flower is the aster. These come from calendar tradition rather than astrology, and the lists vary by country and source.
