About this calculator
The year/month/day difference is calculated calendar-style — counting full years, then full months, then remaining days — rather than dividing total days evenly, which avoids the rounding errors you'd get from assuming every month is the same length.
Total days, weeks and months are also shown for a quick at-a-glance comparison.
