You are correct that much of numerology calculations related to revealing the future rely on the person's birth date.

Numerology predictions reveal tendencies and likelihoods, not certainties.

Calculations with the person's name may reveal some of how the person is likely to relate to, or react to, the tendencies and likelihoods. But calculations with the birth date provide more direct insight.

When wanting to determine what a future holds, a person has to also determine at what point in the future they are interested in — next month? 10 years from now?

These two articles can help you determine the tendencies and likelihoods of the future for any birth date:

• Looking Into the Future
• What Does My Future Hold?

There is a lot to it. Much depends on how far in the future is the place you want an answer for. The articles can help.
