This can't be just any random number logic. There must be a very clear and reasonable logic behind all this. I have gone through some number patterns that are equal to other important numbers to that person. For instance, if that person was born in the year 1999 and he or she has died in the day of 18.9.2018. 1+8=9, 9, 1+8=9 =999. This can't be all random, what do you think about this?
