How this business days calculator counts
- Add or subtract mode starts counting from the day after the start date (or the day before, when subtracting) and lands on the Nth business day. 0 returns the start date.
- Every day from the start date to the end date is checked. Use the two checkboxes to decide whether the start and end dates themselves are counted.
- Days you tick as weekend days are never counted. Pick any combination, for example Friday and Saturday, or Sunday only.
- US federal holidays follow the eleven holidays listed in 5 U.S.C. 6103. Juneteenth is applied from 2021 and Martin Luther King Jr. Day from 1986.
- A holiday that falls on a weekend day is counted once, as a weekend day.
- Dates are treated as plain calendar days, so your time zone does not change the result.
- Dates from 1990 to 2100 are supported. Free to use, no sign-up, no usage limits.
