The bonus starts after you've seen the bonus screen so you can't get it on a race that starts the day before. The bonus screen only appears between races, not during them. However, I think if your first race of the day starts at 23:30 and finishes at 00:05 then I suspect you would get the previous days bonus (but haven't tested it).
