How Age Is Calculated
Your age is calculated by comparing your date of birth with a selected calculation date. The calculator determines the complete years first, then calculates the remaining months and days based on the actual calendar dates.
Age in Years, Months, and Days
Age is commonly expressed as the number of complete years, followed by the remaining months and days. Because months have different numbers of days, an accurate age calculation must account for the actual calendar rather than using a fixed number of days for every month.
Age = Calculation Date − Date of Birth
Then :
✅ Years — Complete years that have passed since the date of birth.
✅ Months — Remaining complete months after the years are calculated.
✅ Days — Remaining days after the years and months are calculated.
