For centuries, the study of numerology has attracted many people with its mystical fusion and excitement. Most modern numerologists believe that each and every number in this universe has some power or vibration, which cannot be expressed solely by a letter or symbol. It was Dr. Julia Steton (1862-1950) who gave the name numerology to the modern science of names and numbers, but the origins of numerological concepts are not clear with any definite details.

Most numerologists believe that Babylon and Egypt are among the earliest civilizations that practiced numerology. There have also been records found in Japan, Rome, China, and Greece indicating the use of numerology and its various techniques. However, the credit for development of modern numerology is given to the Greek philosopher Pythagoras, who was born in Greece in 590 BC. Unfortunately, though, there is very little recorded evidence for this earliest practice of numerology.

Numerology is considered to be one of the earliest forms of metaphysical reading and communication, with only numbers used in this method. The numbers utilized are known as the language of intelligence; in ancient times, people used numbers, markings and scribing methods to communicate, trade, and exchange  ideas. Since those early days, the four perfect numbers 6, 28, 496, and 8128 have been used. 

Pythagoras and Cornelius Agrippa are noted philosophers who contributed much to numerological reading. According to these philosophers, everything in the universe is based on numbers and all the numbers of the tangible or intangible body hold a meaning.

Today, most modern numerologists follow this principle with their own modifications. For example, an individual's birth date may be combined in certain circumstances to illustrate personal traits and strengths. In addition, the date of birth may be combined and examined by means of a simple mathematical calculation, then decrypted to forecast the future events in the life of a person.

There are three major classifications of numerology practiced today: the Chaldean, the Kabbalah, and the Pythagorean. Each of these individual methods utilizes a different method of calculation and each one offers a different perspective about the future events of an individual. The Chaldean system is considered to be the original numerological practice, in which a number is assigned to the sounds of each alphabet. Chaldean numerology makes use of compound numbers and the number 9 is believed to be the holy number in this system, so it is kept separated from other numbers.
