Numerology is the science of using numbers to predict the future or get to know more about a particular person. The date on which a person is born plays a very important role in their life. All events small or big happen on their birthdate or other numbers associated with it. Numerology is connected with astrology as well. All the numbers from 1 to 9 are associated with 9 planets in astrology. Like 1 is for The Sun, 2 for the Moon, 3 for the Jupiter, 4 for Rahu, 5 for the Mercury, 6 for the Venus, 7 for the Ketu, 8 for the Saturn, and 9 for the Mars. So the person whose birthday comes on 1, 10,19, 29 will be having the quality of sun and all the major or small event will happen on these dates. It is the same for other numbers too. In numerology along with a lucky number, other numbers are also being used with it, like soul urge number, destiny number, Karmic Numbers, etc. You can edit your name with Numerology. I myself tried name change with numerology, and so far I found it useful.
