Why are all the days of the calendar month not listed on your menu?

We have found that customers prefer to order by full week increments. Our menus are typically four weeks in length. Most months, this will be close to a calendar month. Sometimes the weeks on the menu get out of sync with the calendar due to holidays and vacations.  We will always send a new menu out a week before the current menu expires. Mark the days you order on your home calendar so you can be sure to track when a lunch is ordered.
