Depends on when your new day starts. For me it's 7:00pm (1900hours).
So I can actually play two days in a row within minutes if I time it right and playing a single hole.
I just look at my timer to see how long I have left to get my round or single hole played before the next day starts. If I already have the green check mark, then I know I'm good to go and if I know I'll be busy for the next day, I may play my round for tomorrow tonight after my clock resets for the new day and then I'm covered until tomorrow night.
