Automated Email Using DATE

Making an excel program that will automatically Email 5 people with either the whole document, a link to the doc, or just an email using the cells to inform them on what needs to be checked. And I don't even know where to start.

There will be a spreadsheet with everyone's name going down in column A, and then in the row next to the name it'll have a date of when they were put on it. It'll then have another date of the time they need to have done certain things, like see the doctor or get a class done, so when the current date reaches the date in the column the cell that is the same date will turn red, and the document will be mailed to 5 of the higher ups to inform them they need to check on this Marine to see if he has accomplished whatever task has expired.

Ive been trying to research a lot of this on my own, but ran into problem where the current outlook version does not suppose the command DATE within an excel, so I need to make a database using multiple excel sheets using Visual Basic(or so I'm told now).
