How it's calculated
The calculator subtracts calendar components rather than dividing total days, which keeps months accurate.
If the day of the target date is earlier than the birth day, it borrows the number of days in the previous month; if the month is earlier, it borrows twelve months from the year count.
Total days lived is the raw difference between the two dates in whole days, which naturally includes leap days.
