2nd decan of Libra: Saturn
Each sign is divided into three decans, 10° slices that the Sun crosses in about ten days each. October 12 falls in the second decan of Libra (about October 3–12), which the traditional Chaldean system assigns to Saturn. Astrologers say that adds discipline, patience and a serious streak.
Saturn brings structure and a long view. People from this decan often mature early and are willing to work slowly toward something that lasts.
The number 12 in numerology

What zodiac sign is October 12?
October 12 falls in Libra, which runs from September 23 to October 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 October 12 a cusp birthday?
Not by the usual definition, which counts the first and last couple of days of a sign. October 12 is day 20 of Libra season, so it is normally read as a clear Libra birthday.
Which decan is October 12?
October 12 is in the second decan of Libra (October 3–12). In the traditional Chaldean system this decan is ruled by Saturn, which astrologers say adds its own flavour to Libra. 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 October?
The modern birthstone for October is Opal and the birth flower is the marigold. These come from calendar tradition rather than astrology, and the lists vary by country and source.
