I am wondering if there is a way to have indesign do date calculations. For instance, I enter a departure date for a trip into the document. The fine print in the document needs to have multiple dates filled in that are all a certain number of days before the departure day. 150 days before, 100, and 60. Is there a way to automate this?
I guess you could use that to do the calculations. You could, for example, have a script that allows you to enter a date and then shows the list of prior-to dates, allowing you to copy them nto your document.
Of course there is much more possible as well.
