Horoscope compatibility is how well two people will match up or get along based on when they were born which determines their astrological sign. A horoscope represents your astrological sign and its description of your traits in your personality, etc. Astrology divides human traits in to groups and then horoscope or astrological compatibility works by comparing your traits with that of another person to determine how well the traits match up. It is a complex field and there are so many things that can play into ones astrological chart if you really go into depth with it. That all being said, each person is unique and if you believe that you’re horoscope truly defines who you are, it could possibly work well for you.
Horoscope compatibility is based on each person's alleged horoscope sign, and it is basically matching the set personality types of each sign with each other. Based on each sign's personality, they are scrutinised to see if they are a good match. One disadvantage of using horoscopes is that it does not consider the individual personalities of each partner and hence is not very accurate.
Horoscope compatibily uses your astrological sign (Gemini/Libra/Sagittarius etc) to determine whether you and partner are going to see eye to eye on specific issues. Signs that are opposite each other on the wheel are said to be perfect matches. They get along and connect on every aspect such as friendship, love/romance, sex, finances, personality etc.
Horoscope compatibility tells you how you and your partner are likely to get along or respond to each other in certain areas of your relationship based on your astrological signs. They can further be linked by your sign's elment and position in the astrological calendar. They include marriage, sex life, personality clashes/harmonies etc.
