9 and 7 Good for Each Other

I assume you're asking the question from a Vedic numerology point of view.

That assumption is based on two things in your question. (1) Your reference to the psychic number as the number 7, which is your birth day of month number. (2) Your reference to the destiny number 9, which is your birth date number.

My expertise is in Pythagorean numerology. Therefore, my response must be based on that. The Pythagorean and Vedic studies are different. Therefore, it may be prudent for you to ask your question of a professional Vedic numerologist.

To clarify terms: In Pythagorean numerology, the destiny number is the name number. The birth date number is referred to as the life path number. The birth day of month number is is referred to as the second life period cycle.

Your life path number is a number with you your entire lifetime. Your second life period cycle number is with you from approximately age 28 through age 54.

The energy the number 9 represents and the energy the number 7 represents are compatible. They tend to support each other. I think that's what you mean when you ask if they are good for each other.
