Questions
Frequently asked questions
Does a compressed week reduce total working time?
No. It redistributes the entered weekly hours across fewer workdays unless the weekly target itself is changed.
What makes Schedule starts important to the
Schedule starts anchors the Compressed Workweek Planner sequence, while Daily start time controls its recurrence or review horizon. Check the anchor before comparing individual dates.
When would a different Daily start time require a fresh compressed workweek planner result?
Change only Daily start time and regenerate the Compressed Workweek Planner. In the Compressed Workweek Planner, the first changed occurrence shows where the revised Daily start time cycle or boundary begins to matter.
Which Daily start time occurrences in the compressed workweek planner deserve a boundary review?
Inspect the first and last Compressed Workweek Planner entries plus any date near a weekend, month end, or listed exclusion. Those positions expose most recurrence-boundary mistakes.
