Daily Plotting Help

Happy Friday! What day of the week does your work-in-progress begin on? Weekday? Weekend? What does that mean for your characters as far as being able to buy something they need (stores close when?), eat (restaurants close at different times on weekdays vs. weekends,) go to a doctor vs. an ER or a dentist, get help from tech support, call their office, or call friends for help (during office hours, they might be unavailable, on weekends, they might be gone or drunk.)
