Numerology is an old science that is based on numbers, as its name suggests. This science forecasts a person's horoscope on the basis of his/her birth number. Every person having his/her specific birth number inhibits the qualities associated with it. The method that is used to know about someone's horoscope is based on the day of the month in which the person is born (Mulank) and the number drawn by that person's name (Namank). Further, this number is used to know more about that person's personality, nature, education, career and many more aspects. Studying all these aspects based on numbers makes it a study called Numerology.
