Yes, you can erase or turn off the date tabs.
I believe the BG below the photos is a single layer, the photos are each a separate layer, the date tabs are all together on a layer, and the embellishments are combined on a layer. The title may be on the same layer as the date tabs, I can't remember.
I used the December quickpages for my current life365, which is on a Sunday - Saturday week. So, I was easily able to turn off, or just erase, the title/date tabs and replace with the proper ones.
