Where the figures come from
This sum uses only the numbers you entered.
How the gap is counted
We count from the older person's birthday to the younger person's: whole years first, then whole months, then the days left over. The gap stays the same for life, though the difference in their ages in years changes by one between their two birthdays each year.
