You can certainly create a journal in a Word document, but don't expect to
insert the date in any sort of automatic way (the best you can hope for is
that AutoComplete will work for you). Any sort of date field used in a
document will either update to the current date when the document is opened
or never change (either way, all your dates will be the same).
How about a document with AutoOpen macro that would go to the end of
the document, insert the current date, select and then unlink the
field?
This seems to work, probably could use some editing:
Sub AutoOpen()
