Days of Week operates like 'Days' except you can limit it to a specific day of week to avoid comparing a Monday to a Saturday. A trend of the last 5 Fridays can help chefs correctly forecast demand to prep accurately, or managers schedule appropriate support staff based on recent business levels.
Note: If you place a DOW trend (such as last 5 Mondays) and pin it to your dashboard, it will always show yesterday's day of week. So when viewing the dashboard on Tuesday, you'll see the last 5 Mondays, on Friday, you'll see yesterday (Thursday) and the last 4 preceding like days.
