Legal glossary/business day

U.S. legal term

business day

A business day refers to a day on which normal commercial or legal activities are conducted, typically excluding holidays or non-working days.

It means a day when people usually go to work or do business. For example, if Monday is a business day, then Tuesday is also a business day, but if there's a holiday (like Thanksgiving), that might not be a business day.

It matters because it establishes the timeframe within which legal actions, filings, or contractual obligations must be completed. It dictates when a court or business can proceed with legal proceedings or execute contractual duties.

This page gives general U.S. legal information, not legal advice, and contract meaning can change by jurisdiction, industry, and clause wording.
