Feb 29 birthdays: in non-leap years the calendar has no Feb 29, so this calculator's exact age "ticks over" the next time the calendar reaches that point — in practice that lands on Mar 1 of a non-leap "as of" year, and on Feb 29 itself in a leap year. This matches standard calendar-difference math rather than picking Feb 28 by convention.
