A detail that trips up exact age calculations
Calculating age in years, months, and days depends on exactly how you count partial months and leap years -- this is why two different age calculators can disagree by a day or two near a birthday. This calculator counts a full year as complete only once the birth month and day have both passed in the current year, which matches how age is conventionally stated.
