OneNote doesn't make it easy if you want to use the date as the title of a section page, but here's how you can do it.

If you wish to add an agenda for each day you can do so and specify start and end times for that as well. Check out the details and download the OneNote Calendar Page Maker here.

As you can see, I have Personal, Professional, and Quick Notes sections in my OneNote. This easily allows me to organize research I need to conduct according to each branch of my life.
