Add or subtract working days from any date. Define the workweek, exclude U.S. federal or custom holidays, decide whether the anchor counts, and generate individual deadlines or recurring workday schedules.
Set the shared work calendar, then choose a calculation mode.
Business-day rules vary by employer, jurisdiction and schedule. Configure the calendar below rather than assuming one universal definition.
One YYYY-MM-DD date per line. Add an optional name after |. Custom dates are combined with the selected holiday preset.

Sep 1, 2026 + 5 workdays = Sep 9, 2026
Aug 3, 2026 + 10 Mon–Fri workdays = Aug 17, 2026

1 inclusive workday from Monday = Monday
Add 5 workdays under a Sun–Thu schedule
Add 3 workdays while excluding Sep 3, 2026
Monday through Friday is common, but it is not universal. Some organizations work Sunday through Thursday, include Saturday, or close on company-specific and regional holidays.
Weekends and holidays remain in the offset.
Disabled weekdays and selected holidays are skipped.
The start-date rule matters whenever a deadline says the anchor is included or counting begins on the next eligible workday.
| Rule | Eligible Monday + 1 business day | Weekend anchor |
|---|---|---|
| Standard | Tuesday | First later eligible day is counted |
| Inclusive | Monday | Weekend cannot count; move to first eligible day |
| Zero business days | Monday | Return the exact anchor |
| Subtract, standard | Previous Friday | Search backward from anchor |
Holiday calendars differ. The U.S. preset uses modern federal observed dates for a standard Monday–Friday schedule, while custom dates can represent company closures, local holidays or another jurisdiction.
| Holiday source | Best use | Important limit |
|---|---|---|
| U.S. federal preset | Modern federal observed dates | Not every private employer closes |
| Custom holidays | Company, state, school or regional dates | User must provide the dates |
| Bank holidays | Financial or national closure planning | Varies by country and region |
| No holidays | Weekday-only calculation | May overcount operational workdays |
The result is highlighted in its month and every skipped date is classified.

Each calculation uses UTC-safe Gregorian date fields. A date counts only when its weekday is enabled and it is absent from the combined holiday set. The engine separately records disabled weekdays and holiday exclusions, then applies the same logic to single deadlines, batches and recurrences.
