Difference Between Psychic Number and Destiny Number

Probably you're using Vedic numerology. My guess is based on the terms used in your question. A Vedic numerologist may be able to provide the answers you're looking for.

This website uses traditional Pythagorean numerology. It has no chart position named "psychic" and the "destiny" position is calculated from the name and not from the birth date.

The day of birth, which your question refers to as the psychic number, is the number of the second life period cycle. Yours began last year and the number 2 influence in that position will last for a total of 27 years.

What your question refers to as the destiny number is the life path number in Pythagorean numerology. It's the same calculation resulting in the number 8, but a different chart name and a different interpretation.
