Definition
The hours of the day during which commercial, banking, professional, public, or other business activities are ordinarily conducted within a given community. The phrase is a community standard, not an individual or employer standard — it refers to the general practice of the locality, not the particular schedule a business or employer has adopted.
The term surfaces in three distinct legal contexts, each with its own practical implications:
1. Negotiable instruments. The hours within which presentment and demand on bills and notes must be made. For instruments not payable at a bank, business hours have historically been interpreted broadly to extend through most of the day and into the early evening. For bank-payable instruments, the window is narrower, generally confined to the bank's own operational hours.
2. Service of process and legal notice. Courts and procedural rules frequently require that service, demand, or notice be made during business hours. What qualifies is determined by community practice, not by when a particular defendant or recipient happens to be open.
3. Employment and wage law. Whether time falls within or outside business hours bears on questions of compensability, scheduling obligations, and off-hours contact. Here the analysis often turns on statute or regulation rather than the common-law community standard.

Common Language
Modern common usage (Wiktionary): The hours and days when a given business is open to the public; conventionally understood as 8:00 AM to 5:00 PM, Monday through Friday.
Historical common usage (Webster's 1913): No independent entry; treated as self-evident from ordinary usage.
The gap matters in legal research. Lay usage treats business hours as either the hours a specific business posts on its door or a rough 9-to-5 shorthand. The legal standard is neither. Courts have consistently held that the phrase refers to the prevailing custom of the community — what businesses generally do — not what any one business or employer chooses to do, and not any fixed clock range assumed to be universal. A researcher who imports the Wiktionary definition into a legal context will likely misread older instruments cases and service-of-process disputes.

Why It Matters in Research
The community-standard definition is the trap. Both editions of Black's and Bouvier's are explicit on this point, but the implication is easy to miss: in historical sources, whether a demand or presentment was timely often turned on fact-intensive inquiry into local commercial custom, not on a fixed time window. Nineteenth-century case law on negotiable instruments is dense with this analysis, and researchers working with that material should expect to find conflicting results across jurisdictions based on differing findings about community practice.
Context collapse is a second hazard. "Business hours" appears across employment law, civil procedure, banking law, and commercial law with surface consistency but meaningfully different underlying tests. An employment regulation using the phrase may incorporate a statutory definition that overrides the common-law community standard entirely. A procedural rule may incorporate local court custom. Do not assume the definition travels across these contexts without checking the governing authority in the specific domain.
Jurisdictional drift is real. The negotiable instruments framework has been substantially displaced by the Uniform Commercial Code in modern practice, which introduces its own timing rules for presentment. Historical sources discussing business hours in the bills-and-notes context predate the UCC and may describe rules that no longer apply in that form.
The employment connection requires a separate analytical lane. Whether time spent by an employee during or outside business hours is compensable under the FLSA is governed by federal regulatory standards — the common-law community definition is not the operative test there.

Historical Dictionary Support
The three source dictionaries converge on the community-standard definition, and the convergence is instructive. Both editions of Black's carry identical language tracing to a Minnesota case, making clear that the employer's schedule is irrelevant to the definition. Bouvier's adds important nuance for the negotiable instruments context: for non-bank paper, business hours run broadly through the day and into the evening hours of rest; for bank paper, the bank's own hours control. This distinction — which modern researchers might not anticipate — was commercially significant in a period when presentment timing determined liability on dishonored instruments.
Bouvier's truncated entry (the source text cuts off mid-sentence on "usual business hours") hints at a further refinement between "business hours" and "usual business hours" that the available text does not complete. Researchers working with Bouvier's in historical instrument disputes should seek the full entry in an unabridged edition.
None of the historical dictionaries address the employment law dimension — that application is a twentieth-century development lying entirely outside their scope.

Jurisdictional Note
Modern procedural rules governing service of process and legal notice often define or incorporate business hours by reference to local rules or statute, which may specify a fixed range rather than deferring to community custom. Researchers should check applicable rules of civil procedure and any relevant administrative code rather than relying on the common-law community standard in procedural contexts.
