Definition
The term of a lease is the fixed period of time during which a tenant is entitled to occupy and use leased premises under the terms of a lease agreement. It begins when the tenant's right of possession commences — typically upon the tenant's entry or the agreed commencement date — and ends on the expiration date specified in the lease. The term is one of the essential elements of a valid lease; without a defined or definable duration, the arrangement may be characterized as a tenancy at will rather than a term tenancy.
The term of a lease is distinct from the date the lease instrument is executed. A lease may be signed weeks or months before the tenant takes possession. The "term" runs only from the point of authorized occupancy, not from the moment the parties put pen to paper.
In commercial leasing, the term also serves as the anchor for calculating rent escalations, tenant improvement amortization, option exercise windows, and renewal rights. In residential contexts, it defines the period during which the landlord's obligation to maintain habitable premises and the tenant's obligation to pay rent are operative.

Common Language
Modern common usage (Wiktionary): "Term" in ordinary English means a limited or defined period of time, or a word or phrase used to describe something.
Historical common usage (Webster's 1913): "Term" carries the sense of a bounded period — "a limited time; particularly, the time for which anything lasts" — and also the specific legal sense of the period for which a court sits or an estate is granted.
The common meaning of "term" as simply a period of time tracks reasonably close to the legal meaning here, but the legal definition carries a precise trigger point that ordinary usage obscures. Colloquially, people treat the "term" as beginning when they sign the lease. Legally, it begins when the right of possession vests — a distinction that can matter for rent obligations, notice periods, and holdover calculations.

Why It Matters in Research
The gap between lease execution and lease commencement is a recurring source of confusion in historical sources and remains practically significant today. Early case law, including the authority cited in Black's, draws a sharp line: the term does not include any period between the making of the lease and the tenant's entry. Researchers working with older materials must be alert to the possibility that courts used "lease" and "term" interchangeably in loose phrasing even when the legal distinction was well established.
In commercial lease research, the term of lease intersects with several other defined concepts — base term, option periods, renewal terms, and holdover periods — each of which may be treated as legally separate from the original term. A holdover tenancy, for example, arises after the term expires and operates under different legal rules. Researchers should not assume that a court's discussion of "the lease term" encompasses renewal or option periods unless the lease expressly so provides and the court has confirmed the inclusion.
For residential leases, the term matters when analyzing statutory protections that apply differently to month-to-month tenancies versus fixed-term leases. Many tenant protection statutes distinguish sharply between the two, so identifying whether a defined term existed — and when it ran — is a threshold question in housing litigation research.
Researchers consulting nineteenth and early twentieth century sources should note that "term" in older property law also carried the meaning of a leasehold estate itself (the "term of years"), which is a related but distinct concept. Context is essential to determine whether a historical source is discussing the duration of occupancy or the nature of the possessory interest.

Historical Dictionary Support
Black's Law Dictionary provides a concise and precise formulation: "term," when used in connection with a lease, means the period granted for the lessee to occupy the premises, and excludes the time between the making of the lease and the tenant's entry. This definition is well-grounded and has not been materially displaced by modern usage — courts continue to enforce the execution/commencement distinction.
What historical dictionary sources generally do not address is the complexity introduced by modern commercial leases, where the "term" may be subdivided into base term and option periods, or where commencement may be conditioned on delivery of the premises, completion of tenant improvements, or a rent commencement date that differs from the possession commencement date. These layered structures are creatures of twentieth and twenty-first century practice and fall outside the scope of classical dictionary treatment. Researchers working with contemporary commercial leases should treat the historical definitions as a floor, not a ceiling.

Jurisdictional Note
Most American jurisdictions follow the same basic principle that the term runs from commencement of possession rather than execution, but statutory definitions of lease terms — particularly for residential tenancies — vary. Some states impose minimum or maximum term limits for certain lease types, and others define "fixed-term lease" by statute in ways that affect tenant rights upon expiration. Researchers analyzing specific tenant protection statutes should check the applicable state's residential landlord-tenant act for any statutory definition that may modify common law principles.
