A Personal Year Number is calculated by combining a person's birth date with the current calendar year, producing a number that shifts annually rather than staying fixed. It's used to identify the general theme or energy of the year ahead, whether it favors new beginnings, rest, relationships, or major change.

How to calculate it:
Add the birth month, the reduced birth day, and the reduced current year together, then reduce the total to a single digit.

Example — Birth Date: April 25, for the year 2026

Month (April): 4
Day (25): 2 + 5 = 7
Year (2026): 2 + 0 + 2 + 6 = 10 → 1 + 0 = 1
Add the parts: 4 + 7 + 1 = 12
Final reduction: 1 + 2 = 3

Personal Year Number: 3
