Satisfying curiocity is not the only objective of Astrology. It has some real practical uses.
1) Finding the right partner: It's not just about match making. When a person is ready for marriage, he/her tries to find a person who is compatible with his/her mind set. Astrology can tell the basic traits of a person, is the person cool tempered, or is he outgoing, would he care for his family or would he spend more time in self grooming.
Health and life expectancy has no substitute. Any body would want their partner to be healthy and with a reasonable life expectancy. People expect to grow old together with their partner.
Luck plays an important role in a person's life. How lucky is the person in consideration, let's say a person has not so strong ninth house, then he would have to struggle in achieving things worth achieving in life. Such a person should find a person with a strong ninth house, this would help in giving a support to this person's luck.
Astrology can tell if the person would work hard or is he lazy. If you want a working partner you better find someone who is hardworking and not lazy, on the other hand if you want your partner to stay in home, than you should find a person who is not so enthusiastic about making his/her career.
Kids are the most beautiful aspect of human life. Sometime a couple has to struggle to get kids. Astrology can help to find whether there are any complications regarding birth of a child in a person's chart. If a person has weak chances of getting kids than its better to find a partner who has strong chances of getting a child.
2) Career: A person can do anything and earn money, live his life. But something that a person is not interested in, can make his work routine monotonous and painful sometimes. Finding the right career is of immense importance, this should be looked into right from choosing the education stream. For example a person who is introvert, hardworking and intelligent, such a person chooses marketing as a career field. His introvert nature would always hinder his career growth and his work can be a big load in his life. This same person if chooses finance or science as a career than he would get the complete chance of using his intellect and abilities. Most of the time career is choosen on the basis of monetary rewards, which is not the right career always. Astrology can provide a hint about what could be the best career field for a person.
3) Child birth timing: These days there a lot of cases of child birth by c-section. When a child comes into this world the planetary position at the time of birth ascertain child's future. Therefore if we have a choice about the time at which a child is born, than should we not choose a suitable time. We can avoid days which are having bad planetary combination like grahan yoga, amavasya etc. Every chart has both strength and weakness, we cannot find a time which only has strengths and no weakness. We can only avoid some very bad yogas.
4) Light in dark times: Every person comes across good and bad times in life. While in bad time a person generally gets disappointed. This person may not know that this period will not last long, thus feeling depressed all the time. If this person finds out that the bad times would be over soon than he gets the hope. Hope is the most potent tool to fight depression. Even if a person is told that you would have problems for say two years, than also a person is prepared, he would be prepared and not live in false hope, do some remedies and stretch through that period.
5) Helps in Taking Risky Decision: Humans are never satisfied, a person may have a good job but still searching for a better one. Sometimes switching jobs can prove to be more problematic than staying in the old job. This generally happens when a person's good time is ending and bad time is about to start, the person makes a wrong decision to switch job. Before taking such decisions it's always wise to consult an Astrologer, if there are good times ahead an Astrologer would give a green signal otherwise not. This would not alter the bad results, but still being in old environment can aid in fighting bad results.
Although there are many more fields where astrology can prove to be helpful, still Astrology is a tool best used when in dire need.
