Sure thing.  Basically I'd like the "date" column to be automatically
calculated so that I can move things around, add extra days here and there,
and not have to edit that column by hand.

| date      | location | activities    | notes                      |
|-----------+----------+---------------+----------------------------|
| 03-16 Tue | moon     | collect rocks |                            |
| 03-17 Wed | mars     | terraform     | this might take a few days |
| 03-18 Thu | earth    | breath air    |                            |

If I wanted to add an extra day on mars I could just enter a new row,
recalculate the forumula, and the dates would be automagically updated.
It's not such a big deal in a small example like this but I'm planning out a
3 week vacation with a fair number of destinations.  I'd like the day of
week to display because some sites are closed on certain days.

It goes without saying that I've spent more time trying to figure this out
than it would actually save so it's more about education at this point :)
