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.

  1. Choose month or year view.
  2. Count all calendar days in the selected period.
  3. Subtract selected non-working weekdays.
  4. Subtract public holidays when the option is enabled.
  5. Subtract custom company holidays.
  6. Avoid double-counting a holiday that falls on a selected non-working day.
  7. Multiply working days by work hours per day when work-hour calculation is enabled.
  8. Show monthly and weekday breakdowns for easier review.

Why DeadlineDays is different

The calculator pages are designed for business review, not keyword-only date content.

Country-specific public holiday data gives each calculation a concrete calendar context.
Custom non-working weekdays and company holidays support workplace-specific schedules.
Regional holiday coverage is used where reliable data is available.
Browser-side calculation, no login, and clear assumptions help users review results before copying or sharing them.
The examples stay grounded in invoices, SLA commitments, shipping promises, payroll cutoffs, and public holidays.
