Our Date of Birth Calculator uses precise mathematical formulas to calculate your exact age:
Age = Current Date - Birth Date
The calculator automatically adjusts for:
Years: Current Year - Birth Year
Y = CY - BY
Months & Days: Adjusted based on:
If Days < 0: Months--, Days += DaysInPrevMonth
If Months < 0: Years--, Months += 12
Total Days: (Current Date - Birth Date) / (24h × 3600s × 1000ms)
