Instructions

How to use this calculator

Enter start and end dates, calendar or business basis, boundary settings, and any excluded holidays.

  1. Define Start date and End date from one Inclusive or Exclusive Deadline Counter reporting period.
  2. Define Counting basis, Include start?, Include end?, and Excluded holiday dates without changing the Excluded holiday dates unit.
  3. Assemble the Inclusive or Exclusive Deadline Counter and reconcile its headline with component values.
  4. Record Excluded holiday dates beside the Inclusive or Exclusive Deadline Counter output whenever it changes precision or scope.
  5. Verify the Inclusive or Exclusive Deadline Counter warning, then reconcile Excluded holiday dates with its external requirement.

Interpretation

Interpreting the headline metric

The result is a count, not a legal interpretation. Boundary language in the governing rule controls.

Verify Start date, End date, and Counting basis beside the Inclusive or Exclusive Deadline Counter headline; Excluded holiday dates reveals rounding across the component values.

Calculation

Method used

Every eligible date in the range is counted, then the start and end are included or excluded according to the selected rules.

Count eligible dates in the range after applying start-boundary, end-boundary, weekend, and holiday rules.

The Inclusive or Exclusive Deadline Counter evaluates Start date, End date, and Counting basis separately; store Excluded holiday dates visible outside any percentage, rate, or total.

Calculation method last reviewed: June 21, 2026.
