Astrological compatibility charts are designed to compare birth signs for compatibility in the areas of romance, career, and all sorts of other things. It can neither be proved that it truly works nor disproved that it is just myth, but there are some people who swear by these charts and will never make a crucial decision in their life without first consulting their horoscope, so it is basically up to you to either believe in them or not. One thing for sure is that the many people who are responsible for creating these charts have become quite wealthy, so something must be working for them.
As for romance, maybe some people believe that they can choose their soul mate by using these charts and comparing birth dates and also the time of birth. For instance whether it was in the morning, or midnight, or afternoon, because all these make a difference in deciding how you choose the right person who is most compatible to you as these are all factors in making you who you are according to astrology. Others use these charts to make decisions such as is the time right for them to change their jobs or go on that job interview and things like that. Basically it is really up to the individual and his or her beliefs that probably play an important part as to whether these charts actually work.
Women tend to be more prone to using these charts than men, because they are more inclined to look towards the spiritual world and are the ones who would quickly believe in their astrology to help them make the right choice when it comes to romance. To these women choosing a partner using these charts would mean that they absolutely cannot go wrong, because they actually believe that they are going to select their perfect soul mate, the one person that they are supposed to be with for the rest of their lives. Most men on the other hand even if they did believe in this sort of stuff would much prefer to go out and have a chance encounter with someone who may well turn out to be their perfect soul mate.
So as to whether astrological compatibility really works, it is left to you the individual to decide because it is really nothing more than what one believes in. So if you are not one to check your horoscope in the newspapers on a daily basis before you even make a decision, then this will definitely not be your first choice on how to choose that perfect someone. On the other hand if you are the type of person who just cannot make a decision without consulting your horoscope first, then using this method will probably give you the best choice of deciding who your perfect mate should be.
