The Mathematics of Age Calculation: Understanding the Process
📅 Basic Age Formula
The fundamental calculation involves subtracting the birth date from the current date, but this requires careful handling of months with different lengths and leap years.
📅 Leap Year Handling
Leap years add an extra day (February 29), which affects age calculations for people born on or around this date.
📅 Total Time Calculations
For maximum precision, we calculate total days using millisecond differences, then derive all other units from this base calculation.
