Hello rhubarb lady. If you really want to have an accurate reading of your life's destiny the time of birth is important. Having the day, month and year is 75% ok. I know it is difficult to convince everybody about the benefits of FS. But again it should be a collective decision coz it will benefit everyone not just you. Are you experiencing any negativities in your life? Then, FS is one of the answer. By balancing the negative and positive Qi (Yin and Yang) you will attain prosperity, good health etc. It is not a DIY process coz if you activitate the wrong star misfortune etc. will occur. That is why a professional FS consultant is needed. But if you want to know more about Feng Shui you need to start by reading good books on Feng Shui (go to....
www.masteryacademy.com). When you are ready you should attend a course so you can learn it first handfrom the experts. Remember, patience is a virtue. Learning feng shui is an art and the great masters took a lifetime to be good at it. You do not become an expert overnight. I hope I've answer some of your queries. Ciao.
