Step-by-Step Worked Example
1. Mapped Variables
Birth Date
1990-01-01
Target Date
2026-06-18
2. Equation Substitution
Equation with standard inputs
Interval = 2026-06-18 minus 1990-01-01
3. Calculation Steps
Step 1: Compute Year baseline difference

Base Year difference: 2026 - 1990 = 36 Years

Step 2: Adjust Months difference boundaries

Month difference: 5 - 0 = 5 Months

Step 3: Align Days and handle month offsets

Calculated Exact Age: 36 Years, 5 Months, 17 Days

Final Resolved Calculated Age36 Years, 5 Months, 17 Days
