How the Age Calculator Works
Calculating an individual’s exact chronological age involves more than simply subtracting the birth year from the current year. Our chronological age calculator measures the complete calendar difference between your date of birth and a target date, accurately factoring in variable month lengths (28, 29, 30, or 31 days) as well as leap years.
Understanding the Age Calculation Formula
To compute chronological age manually, the calculation begins with the days. If the target day is smaller than the birth day, days are borrowed from the preceding month. Next, months are calculated; if the target month is earlier in the year than the birth month, 12 months are borrowed from the target year. Finally, the remaining years are subtracted to give the exact breakdown in years, months, and days.
