The Sun enters the Zodiac sign Sagittarius at November 23, 2018 and leaves it on December 21, 2018. Sagittarius is the ninth astrological sign in the Zodiac, which spans the zodiac between the 240th and 269th degree of celestial longitude. Sagittarius is seasonally associated with the transition from autumnal moisture to mid-winter dryness. Because its period indicates a change of season, it is known as a "mutable sign" describing an instinct toward change and an easy ability to modify or adapt to the demands of the environment.
The sign is governed by Jupiter, a planet which is symbolically associated with temperate qualities which loosen, relax and expand. Sagittarius is also linked with the "element of fire," which represents outgoing, action-oriented energy that seeks spontaneous expression. As the mutable fire sign, governed by an expansive planet, the symbolic focus of the sign is connected to the principle of exploration and evolution. Correspondingly, Sagittarians are reputed to be drawn toward travel and philosophy, and to enjoy social contacts, meeting new people and exploring other cultures. They are said to be highly intelligent, broad-visioned, tolerant in their views, mainly concerned with the "big picture" but with little patience for the details.
Generally, the qualities of Sagittarius are considered to be compatible with these signs: Aries and Leo, and to a lesser extent with these signs: Gemini, Libra and Aquarius. Compatibility based on sun-sign alone is considered to be only a very general guideline. The branch of astrology dealing with interpersonal relationships is called Synastry. In this, astrologers analyse the horoscopes of both parties being considered with particular reference to the positions of the Sun and Moon, and Venus and Mars. (With material from: Wikipedia)
