How Age Is Calculated
Our Age Calculator determines your exact age by computing the difference between your date of birth and the target date. It accounts for varying month lengths and leap years to give you a precise result in years, months, and days.
Method
Exact Age
Age = Target Date minus Date of Birth (accounting for month/day carry)
Next Birthday
Days until next birthday = Next anniversary minus Today
