How Astrology Determines the November 21 Sign
Western tropical astrology divides the ecliptic into 12 equal 30-degree segments starting at the vernal equinox. The sun's geocentric apparent longitude determines the sign placement for a given date. For November 21, the sun is usually near the 27th to 29th degree of Scorpio, just before it enters Sagittarius. Exact degree calculations require ephemeris data and precise birth time, which professional astrologers and chart calculators use to place the sun in the correct sign.
Sidereal astrology, used in Vedic and some other traditions, shifts the zodiac signs by roughly 24 degrees due to precession of the equinoxes. In sidereal systems, November 21 may fall in Libra rather than Scorpio, depending on the ayanamsa offset. Most popular horoscope sources in the United States use the tropical zodiac, which keeps the sign boundaries aligned with the seasons rather than the constellations. Astro-Datab
