Hi,

It's htat time of year again and I'm putting together course syllabi.  I
would really love to be able to dynamically calculate dates in a
spreadsheet, e.g.:

|Topic 1|Date1|Description1|
|Topic2|Above Date + 7| Description2|
|Topic3|Above Date + 7| Description3|

Is there a way for me to do that?  Even better would be to be able to do the
same thing in headlines, e.g.:
** 0. <2011-09-13 Tue>[[file:./syllabus/what-is-history-for][What is History
For?]]
** 1.  <Last Date Plus 7>
[[file:Syllabus/history-and-the-public-sphere][History and the Public
Sphere]]

but there I'm in deeper water, I think.

Thanks as always,
matt
