How this is calculated
The total days count is a straight subtraction of the two dates. The years / months / days breakdown uses real calendar arithmetic, borrowing from the preceding month when the end day is earlier than the start day.
Dates are treated as inclusive of the start day and exclusive of the end day, which is the standard convention for date differences.
