If you do not wish to change this field, skip this step and proceed to the next.
The default value for this field is Saturday. Data through the end of the stop day is collected and included in the weekly summary.
When the start or stop day is changed for the week, the data from the old start day through the new stop day for the week is archived.
If possible, make any changes to the Week Start Day and Week Stop Day after CMS performs the weekly archive. This change is not possible for a seven-day week. When the start and stop day for the week are changed, the current week will contain the data item, INCOMPLETE, to indicate that the data for this week is peculiar since the definition of that week was changed.
If the Week Start Day and Week Stop Day are identical, data for only one day will be collected for that week.
