Because I'm uncertain exactly what you're asking, I'll respond in two ways.

1. There is a universal year number, which you may be referring to. The number changes every year and indicates the general tendencies and likelihoods of the human race for that year.

   Use the universal year number calculator to determine the number for specific years.

   The Universal Numbers vs Personal Numbers article talks about the difference between universal and personal numbers.

2. With Pythagorean numerology, which I practice, there is no universal number in the personal numerology chart. And no numbers need to be followed.

   The chart numbers indicate tendencies and likelihoods related to a person's life and who they are.

   There are numerology core numbers, but no one individual number that is determined to be the most important.
