Which federal holidays does this calculator exclude?

All 11 US federal holidays: New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, and Christmas Day. Each is calculated using its official date rule and the observed date when the holiday falls on a weekend.

Does it handle observed holiday dates correctly?

Yes. When a fixed-date holiday falls on Saturday, the observed federal holiday is the preceding Friday. When it falls on Sunday, the observed holiday is the following Monday. The calculator uses observed dates for the exclusion, not the calendar date of the holiday.

Why does my contract say 5 business days but the calendar shows 7?

Business day calculations skip weekends and holidays, so a 5-business-day period can span 7-10 calendar days depending on when it starts and what holidays fall in the range. The tool shows exactly which days were excluded, giving you an audit trail for deadline disputes.

What about legal and court deadlines?

State courts often observe additional local court holidays not in the federal calendar. Use the custom holiday field to add your state court's holiday schedule. For formal legal deadlines, always verify against the court's official calendar, this tool is a planning aid, not a substitute for professional legal advice.

What happens when two federal holidays fall in the same week?

Both are excluded. The most common occurrence is Thanksgiving week, where Thanksgiving (fourth Thursday of November) and Christmas (December 25) occasionally interact with other December dates. Thanksgiving week alone removes one business day; if Christmas falls on a Friday that year, the week before also loses a day to the observed holiday. The tool lists each excluded holiday separately by name and date, so you can see precisely which holidays affect any given range rather than just seeing a reduced count without explanation.

Can I use this tool to verify if a specific date is a federal holiday?

Yes. Set both the start and end date to the same calendar date. The output will show either 1 working day (if that date is a business day) or 0 working days with the excluded holiday listed by name (if it is a weekend or federal holiday). This is a quick way to confirm whether a specific date is a federal observed holiday before scheduling a deadline or appointment.

How this tool works

The tool iterates day-by-day through the selected range, applying three exclusion tests in sequence.

Worked example

Range: January 1, 2025 to January 31, 2025 (inclusive both ends) Total calendar days: 31 Weekend days: January 4-5, 11-12, 18-19, 25-26 = 8 days Federal holidays in range: January 1, 2025 (New Year's Day, Wednesday), excluded January 20, 2025 (MLK Day, 3rd Monday of January), excluded Total excluded: 8 weekends + 2 holidays = 10 days Working days: 31 - 10 = 21
