Run the baseline calculation first, then compare the result to a manual spot-check. This helps catch off-by-one errors in building a timeline around a key event.
- Confirm the official start date and end date for your scenario.
- Select the counting rule that matches inclusive vs. exclusive counting and calendar vs. working days.
- Run the calculator and review the breakdown.
- Save the result with the inputs and assumptions for reuse.
Examples
- Example reminder: save the input dates October 12, 2026 and January 9, 2027 along with the rule set so others can replicate the result.
- Example walkthrough: start on October 12, 2026, end on January 9, 2027, and note whether weekends are included for building a timeline around a key event.
- Example summary: October 12, 2026 → January 9, 2027 gives a range you can cite in notes, emails, or status reports.
