The year of birth generally has little force with purpose. Any force the year of birth provides applies to others born in the same year.

The full birth date is considered when calculating the person's life path. Your life path number is a 3, a number which tends to keep you involved socially with personal artistic expression.

Both the life path number and the destiny number are generally considered when discussing purpose. The destiny is calculated from the name. Unfortunately, without your full name at birth I am unable to calculate a destiny number.
