Calculate a date moved forward or backward by weekdays. The calculator runs entirely in your browser and pairs a focused answer with the method, assumptions and the related tools worth checking next.
Your inputs stay in this browser tab. Nothing is sent to a server to produce the result.
Review the inputs and select Calculate.
Enter a starting date and a number of business days to add or subtract. The tool steps one calendar day at a time in that direction, skipping the weekend pattern you choose and any public holidays in the calendar you select. It reports the landing date and its weekday, how many public holidays were skipped and how many calendar days the shift spans in total.
Each step moves one calendar day. Days in your chosen weekend pattern never count, and neither do public holidays from the selected calendar; only the remaining days reduce the amount left. A negative amount steps backward under the same rules, and the starting date itself is never counted.
Friday 2 January 2026 plus 5 business days, with a Saturday–Sunday weekend and no holiday calendar: the weekend of 3–4 January is skipped, the five counted days are 5–9 January, and the date lands on Friday 9 January 2026 — 7 calendar days elapsed.
Only holidays in the selected calendar are skipped; regional, company and one-off holidays are not included. A shift of 0 business days returns the starting date unchanged, even if it falls on a weekend or a holiday.
Enter the starting date and the number of business days to shift it by. Each step below is a short action rather than a wall of explanation.

Enter the date to shift from — the starting date itself is never counted.
Enter the shift amount; a negative amount steps backward. The Weekend pattern and Holiday calendar you choose decide which days are skipped.
The landing date and its weekday: Friday 2 January 2026 plus 5 business days, skipping the 3–4 January weekend, lands on Friday 9 January 2026 — 7 calendar days elapsed.
Use exact source inputs, keep the reference date visible and verify any official rule separately.
Set the reference date to the event that actually controls the decision, not to today.

Friday 9 January 2026. With a Saturday-Sunday weekend and no holiday calendar, the weekend of 3-4 January is skipped, the five counted days are 5-9 January, and the shift spans 7 calendar days in total.
Yes. A negative amount steps backward under the same rules - 5 business days before Friday 9 January 2026 lands back on Friday 2 January 2026.
Holidays in the selected calendar are skipped as well as weekends. Friday 16 January 2026 plus 1 business day lands on Tuesday 20 January with the United States (federal) calendar, because Monday 19 January is a federal holiday; without a calendar it would land on the Monday. Only holidays in the selected calendar are skipped - regional, company and one-off holidays are not included.
A shift of 0 returns the starting date unchanged, even if it falls on a weekend or a holiday.
