About this tool
This page opens the business-day calculator focused on its core two-date question: given a start date and an end date, how many business days fall strictly between — or within — them. Both date fields are ready for you to fill in.
The include-start and include-end checkboxes matter more than they first appear: a contract that runs "from the 1st to the 15th inclusive" counts differently from one that runs "from the 1st, not counting the 15th." Toggle each independently and watch the count adjust.
Add any holiday dates that apply to your situation in the holidays box, one ISO date per line, and they are excluded from the business-day total alongside weekends. The calculation also shows the raw calendar-day span for a quick sanity check.
Example. 2024-01-01 through 2024-01-05, both endpoints included and no holiday lines, counts 5 business days. The calendar gap on the detail line is 4. Adding the holiday 2024-01-01 drops the business count to 4.
Limit. Saturday and Sunday are the only weekends. Any other closure counts only when you paste that ISO date. The calendar-day number is the difference of the two dates, not an inclusive day count.
