I assume you are referring to the date number, the number obtained when the date is calculated to its foundation number. The number is also referred to as a company's life path. The company life path reading tool can be used to do the calculations.

I'm also assuming you are incorporating a business. The number 8 is generally the best business number. But it does also depends on what type of business you are anticipating.

If the business is a restaurant, for example, then the number 6 may be the best, especially if it's a family restaurant. The number 2 may be better if the restaurant appeals exclusively to romantic settings.

On the other hand, if it is not a business you are incorporating, then the 8 might not be applicable. A non-profit, service organization, for example, may do well with a 6 life path number, or a 9 life path if the orientation is worldwide benefits to humanity.

Once you have determined the number, then the company life path reading tool can be used to see which dates calculate to that number.
