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
Generate recurrence dates then apply workday and blackout rules
Nominal dates follow the interval; unavailable dates shift forward to the next allowed workday.

Schedule anatomy
What sets the completion date
Hours, daily capacity, workweek, and exclusions each affect timing.
Final date
—Last adjusted overtime occurrence.
Total overtime
—Hours across all occurrences.
Shifted dates
—Occurrences moved by workday rules.
Decision takeaway: Use the schedule as a capacity plan, then confirm approval and rest requirements.
Practical applications
Decisions this calculator is designed to support
Month-end backlog
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.

Overtime Hours Recurring Date Calculator FAQ
Are weekends counted?
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.
Can the last day be partial?
Yes. The final day's planned hours are capped at the remaining requirement.
