I know the \date command inserts a date in the title, but as I keep working on this document of mine I want to be able to keep a record of what I wrote on each day. I've been simply writing the date now every time I write every day, but I was wondering if there was a command I could use to place the date in a less obtrusive part that's not the body of my document.
I would recommend you to use a version control system (VCS) to keep track of changes on your document. VCS are not only for programming source code, it works great on LaTeX document also. I have used VCS for my own documents.
There are currently a few that you could choose from:
There maybe more, but those are the ones I have used.
