How do I display durations as years and months?
The "Duration" format in Numbers_09 seems to work for weeks, days, and smaller increments of time. I am trying to get the display function to show years and months. This is for autocalculations of ages for birthdays, but would be also useful for the length of time between recurring events (colonoscopies?). How to do this?
