How to use
Translate the requirement into dated work capacity
- Enter the actual planning start date.
- Use a sustainable overtime cap.
- Match the real workweek.
- Exclude known unavailable days.
Calculation logic
Capacity and calendar availability are separate constraints
Required workdays come from hours divided by daily capacity. Calendar span then accounts for nonworking days.
The schedule never assumes every calendar day is available.
Calculation method
Count capacity days and advance through the entered work calendar
The calculator divides hours by the daily cap, then advances over available weekdays and exclusions.

Schedule anatomy
What sets the completion date
Hours, daily capacity, workweek, and exclusions each affect timing.
Workdays required
—Days carrying planned overtime.
Completion date
—Last scheduled overtime workday.
Average daily load
—Required hours spread across scheduled days.
Decision takeaway: Use the schedule as a capacity plan, then confirm approval and rest requirements.
Practical applications
Decisions this calculator is designed to support

A team allocates overtime across normal business days.
What the result clarifies: The calendar exposes whether the deadline is realistic.
Holiday week
One unavailable workday falls inside the plan.
What the result clarifies: The exclusion shifts the completion date instead of increasing daily load.

Only when the entered workdays per week includes them.
How are holidays handled?
The entered count removes the earliest scheduled workdays as a planning approximation.
