Covers all 11 US federal holidays, computed algorithmically for any year. Fixed-date holidays use observed rules (Sat→Fri, Sun→Mon). Floating holidays (MLK Day, Presidents' Day, Memorial Day, Labor Day, Columbus Day, Thanksgiving) are calculated from their nth-weekday rules. Federal holidays apply to federal government employees; private employers are not legally required to observe them.
Formula
Working Days = Weekdays − Federal holidays falling on weekdays
Count all Monday–Friday days in the range, then subtract US federal holidays that fall on those weekdays. When a federal holiday falls on a Saturday, the preceding Friday is observed. When it falls on a Sunday, the following Monday is observed. This calculator uses the correct observed dates for any year.
Worked Example
Scenario: A New York vendor quotes a 10 working day delivery window starting Monday 23 November 2026.
Thanksgiving falls on Thursday 26 November 2026 — one federal holiday within the first week of the window.
10 working days + 1 Thanksgiving holiday = 11 weekdays forward
Result: deadline falls on 7 December 2026
In practice, many US businesses also treat the Friday after Thanksgiving (Black Friday) as a non-working day, even though it is not a federal holiday. Add one extra day as a buffer if your counterparty is in the US and the window spans late November.
Common Mistakes
- Assuming all US businesses close on federal holidays. Federal holidays are mandatory only for federal government employees. Private sector employers set their own holiday schedules. Always confirm with your counterparty which days they are actually closed.
- Missing the Black Friday informal closure. The Friday after Thanksgiving is not a federal holiday but is treated as a non-working day by a very large proportion of US businesses.
- Forgetting the Saturday/Sunday observed-date shift. When a US federal holiday falls on a Saturday, the preceding Friday is observed. When it falls on a Sunday, the following Monday is observed.
