How Days Are Counted
Calendar Days vs. Business Days — Know the Difference
Calendar days
Every day counts, including weekends and holidays. Common in contracts, statutes of limitations, and personal scheduling.
Business days
Weekends and federal public holidays are excluded. Common in court filings, regulatory submissions, and employment law. When a raw deadline lands on a weekend or holiday, it automatically rolls to the next (or prior) valid business day.
Important:Our deadline calculator applies these rolling rules automatically. However, always double-check against your court’s standing orders — some jurisdictions follow modified rules.
Public Holiday Reference
U.S. Federal Holidays Excluded in Business-Day Mode
Every business-day calculation cross-references the official U.S. federal holiday schedule.
Fixed-date holidays
New Year's Day (Jan 1) · Independence Day (Jul 4) · Veterans Day (Nov 11) · Christmas Day (Dec 25)
Variable-date holidays

Frequently Asked Questions
Everything you need to know about legal deadline calculators, court calendar tools, and timely filing
