The Destiny Number in a numerology chart is calculated using a person's full birth name. This is the full name that appears on their birth certificate- unless they were adopted shortly after birth and their name was changed. In that case, the new name can be used. Write out the full name with space below the letters to write the number that corresponds to each. A, J and S are represented by the number 1. B, K and T are represented by the number 2. C, L and U are the number 3. D, M, and V are the number 4. E, N and W are 5. F, O and X are 6. G, P and Y are 7. H, Q and Z are 8. I and R are 9.

In order to calculate the Destiny Number, add the numbers together for each part of the name, reduce the total if it is not between 1 and 9 (or 11 or 22, the master numbers). Then add the reduced results from each part of the name together and reduce again if necessary. For the name Jane Doe Smith, you would start with Jane- which would be 1 + 1 + 5 + 5 or 12, which reduces to 3. Doe would be 4 + 6 + 5 or 15, which reduces to 6. Smith would be 1 + 4 + 9 + 2 + 8 or 24, which reduces to 6. Add them together and 3 + 6 + 6 or 15, which reduces to 6. Jane Doe Smith's Destiny Number would be 6.

For those who have a Destiny Number of 4, their life will be devoted to service, management and order. They will be ruled by an earthy practicality and be willing to put forth all of the hard work that it takes for a project to be successful. They are very patient and detail oriented, excelling in the fields of engineering, manufacturing or a medical field. If a job involves organizing, regulating and tenacity this person will feel right at home and excel. They are able to succeed at even the largest of tasks. It is possible that their organization and attention to detail can cross the line into obsession. This person is so meticulous in all that they do that it can be hard to live up to the ivory towers they tend to build- for them and those around them.

Those with a Destiny Number of 4 have very high moral standards and expect their friends to live up to them as well. Those who fail will be met with obvious disappointment. They seek out others who seem likely to share their practical and moral nature. The negative aspects of this number can include dominance over others and bossiness. They can become frustrated when placed in a situation where their abilities are limited. There can be an eccentricity and a stubbornness surrounding these unusual characteristics or opinions. Their opinions are so strong they may become biases.
