Best used for
- Operational due datesAdd a fixed number of working days to a start date for internal planning.
- Vendor and shipping timelinesEstimate when a business-day promise may land after weekends and public holidays are skipped.
- Review windowsPlan non-legal approval, QA or content-review periods around holidays.
Formula and method
The calculator moves forward one local calendar date at a time and counts a date only when it is not excluded by your weekend and public-holiday settings. If the start date is counted, it can be day 1 when it qualifies.
Skipped holidays
| Date | Weekday | Local name | English name | Country | Scope | Types / weekend |
|---|---|---|---|---|---|---|
| Run the calculator to load skipped holidays. | ||||||
Example
If you add 10 business days from a Monday and there are two weekend days plus one weekday public holiday before the deadline, the due date lands later than 10 calendar days after the start.
Limitations
Holiday data is fetched from Nager.Date. This is not legal advice. Deadline rules can vary by contract, jurisdiction, court rule, delivery method, business practice and time-of-day cutoff. Verify official rules before relying on a legal, payroll, HR or compliance deadline.
