Recurring resource calendar
Week-by-week occupancy heatmap with event slots and blackout capacity
Each cell shows scheduled load against parallel resource capacity; the blackout week collapses demand rather than hiding it from the plan.
Weekly capacity register
Recurring event load, attendance, and resource utilization
Compare planned events, expected attendance, active hours, available hours, utilization, and unused capacity for every week.
| Week | Events | Expected attended | Active hours | Available hours | Utilization | Unused capacity | Status |

Schedule setup
Plan the resource calendar, not only event count
- Choose the number of weeks and events per week.
- Include setup and room reset time.
- Count truly parallel resources.
- Enter their usable weekly hours.
- Identify a blackout week explicitly.
Occupancy logic
Parallel rooms increase capacity but do not shorten each event
Resource capacity is a weekly pool, while each event still occupies duration plus setup/reset.
Attendance affects expected delivered events but not the reserved room time in this model.
Calculation method
Convert every event into occupied resource time before checking capacity
Duration plus setup/reset is multiplied by weekly event count. Parallel capacity equals resources times available hours. A blackout week removes its events and records the lost schedule volume.

Schedule diagnostics
Distinguish calendar load from delivered participation
The model exposes reserved hours, expected attended events, blackout loss, and idle capacity separately.
Reserved event count
—Events remaining after blackout removal.
Delivered expectation
—Attendance-weighted occurrence count.
Peak pressure
—Highest weekly utilization.
Unused resource time
—Capacity not occupied across the horizon.
Decision takeaway: Attendance changes expected delivery; it should not be used to release a room unless cancellation is known before the reservation deadline.
Capacity checks
Confirm what each resource hour represents
- Rooms and facilitators may not be interchangeable.
- Setup can require exclusive occupancy.
- Blackout events may need rescheduling.
- Daily clustering can fail even when weekly hours fit.

Practical applications
Decisions this calculator is designed to support
Recurring training program
Two instructors share a six-week schedule with three sessions per week.
What the result clarifies: The heatmap reveals whether weekly capacity is balanced and how one blackout changes delivery.
Community room series
A venue wants to separate reserved hours from expected attended workshops.
What the result clarifies: The register prevents attendance assumptions from understating room occupancy.
Worked example
Current-input substitution and reconciliation
Model limitations
The weekly-pool model does not assign exact clock times, check daily conflicts, optimize resource matching, reschedule blackout events, price overtime, or model variable event duration.
Recurring Event Schedule Calculator FAQ
Does attendance reduce reserved hours?
No. Attendance changes expected delivered events, not scheduled occupancy.
What does a blackout week do?
It removes that week's recurring events from the current schedule.
Can utilization exceed 100%?
Yes; that identifies a weekly capacity shortfall.
Why can weekly capacity pass while a day fails?
This model pools hours across each week and does not assign exact daily times.
