as that's when most people drop them if they either don't go or held the reservation just in case. Additionally, go to wherever you want to eat early and ask to get put on a list. Walk-ins can happen, at least they can at Disneyland. With that said, seeing as how Disneyland caters to locals as WDW caters to out of town travelers, I imagine the likelihood of people letter go of their dining reservations the day prior is much less.
