Personal and business dating service Helpmates by Birthright is based on a unique technology called Birds of a Feather. This algorithm is used for matching partners for any type of relationship: love, sex, friendship, family, business, leisure, hobbies or some specific projects. Matching in our dating algorithm is based on a single criterion – client’s belonging to a particular subtype (one of 293 subtypes of the biological type Homo sapiens). Yes, this matching uses the exact date of birth of a client (see F.A.Q. related to date of birth here), but this has nothing to do with astrology or esoteric knowledge. This technology was created on the basis of scientific research, where a date of birth indicates phenological cycles and is in no way connected with the influence of celestial bodies, planets, numbers, etc. These studies are based on strictly scientific methods and data from many natural sciences (such as biology, zoology, mineralogy, botany, hydrology, soil science, etc.) and humanities (linguistics, psychology, cultural studies, etc.). These studies were carried out for over 40 years and tested for over 25 years (data for 2019). Please refer to the F.A.Q. if you are interested in more detailed information about these studies.
