Monthly capacity comparisons
These cases use a whole-period count to compare staffing capacity, operational availability, or processing workload between months.
Selected month and adjacent capacity comparison
Compare the selected month with the month before and after it under the same workweek, holiday, closure, and hours settings.
Fixed example: May-July 2026, United States, Monday-Friday, verified federal closure snapshot, eight hours per day, three supplied people, and 16 supplied leave hours in June.
| Period | Calendar days | Working days | Public holidays | Organization closures | Schedule hours per person | Team capacity |
|---|---|---|---|---|---|---|
| Previous monthMay 2026 | 31 | 20 | 1 | 0 | 160 | Monthly leave not supplied - capacity unknown |
| Selected monthJune 2026 | 30 | 21 | 1 | 0 | 168 | 488 |
| Next monthJuly 2026 | 31 | 22 | 1 | 0 | 176 | Monthly leave not supplied - capacity unknown |
Compare the selected month with the month before and after it under the same workweek, holiday, closure, and hours settings.

How working days are counted
DeadlineDays starts with every calendar day in the selected month or year, then removes the dates that should not count as working days.
- Choose month or year view.
- Count all calendar days in the selected period.
- Subtract selected non-working weekdays.
- Subtract public holidays when the option is enabled.
- Subtract custom company holidays.
- Avoid double-counting a holiday that falls on a selected non-working day.
- Multiply working days by work hours per day when work-hour calculation is enabled.
- Show monthly and weekday breakdowns for easier review.
How a monthly workday total is formed
The period summary combines eligible weekdays and holiday exclusions, then keeps estimated hours separate from the day count.
- Month and year modes enumerate every date in the selected period rather than extrapolating from an average month.
- Changing the working-week pattern can make Sunday eligible or remove a weekday that another organization would count.
- Public and custom holiday exclusions show why two months with the same number of calendar days can have different capacity.
- Estimated work hours multiply the resulting day count by the chosen daily hours and do not include leave or overtime.
Monthly capacity verification checklist
Confirm the period, country, working-week pattern, public and company holidays, and daily-hour assumption before comparing staffing capacity.
