Definition
The running of the statute of limitations refers to the progressive passage of the time period prescribed by a limitations statute — the clock ticking from the moment a cause of action accrues toward the deadline by which a claim must be filed. When the full period has elapsed without a claim being brought, the statute is said to have "run," and the right to sue is ordinarily extinguished or barred.
The phrase is procedural shorthand for a dynamic process rather than a fixed moment. It encompasses the start of the limitations period (accrual), any events that suspend or delay it (tolling), any events that restart it (revival), and its ultimate expiration. Saying the statute "has run" means the deadline has passed. Saying the statute "is running" means the period is in progress. Saying the statute "has not yet begun to run" means accrual has not yet occurred.

Common Language
Modern common usage (Wiktionary): "Running" in ordinary English means moving continuously, operating, or being in progress. A clock runs; a program runs; a race is run.
Historical common usage (Webster's 1913): "Run" includes the sense of passing or flowing, as in the running of time — "the days run on."
The common meaning of "running" captures movement through time, which is precisely how the phrase works legally. However, the legal usage carries freight that the ordinary sense does not: the running can be stopped (tolled), restarted, or never begun depending on facts the layperson would not anticipate. A researcher encountering "the statute has run" in a legal text should not treat this as a simple statement about elapsed calendar time — it is a legal conclusion that depends on accrual, tolling, and revival doctrines working together.

Common Confusion
Running of the statute of limitations is frequently conflated with the related but distinct concept of a statute of repose. Both involve time limits on claims, but a statute of repose runs from a fixed external event (such as the date of manufacture or completion of construction) and generally cannot be tolled. A statute of limitations runs from accrual of the cause of action and is ordinarily subject to tolling, discovery rules, and equitable exceptions. Saying the statute "has run" tells a researcher nothing about which type of time bar applies — a critical distinction when researching whether any exceptions might revive the claim.
The phrase should also not be confused with the mere expiration of a deadline. Running describes the entire arc; expiration describes only the endpoint.

Why It Matters in Research
This phrase functions as a legal conclusion embedded in a procedural framework. Researchers encountering it in historical sources, pleadings, or judicial opinions need to work backward to three prior questions: When did the period begin to run (the accrual question)? Was the running ever suspended (the tolling question)? Was it ever restarted (the revival question)? The phrase itself answers none of these — it merely announces a status.
Historical sources require particular care. Accrual rules have shifted significantly across time and jurisdiction. The "discovery rule" — under which a statute does not begin to run until the plaintiff knew or should have known of the injury — was not uniformly adopted until well into the twentieth century. Older cases saying a statute "has run" may have applied an accrual standard that would not apply today. Researching a historical claim requires anchoring the accrual analysis to the law as it stood at the relevant time, not projecting modern discovery-rule assumptions backward.
In tax research, "running" takes on additional precision. Tax limitations periods for assessment and collection are governed by the Internal Revenue Code and have their own suspension events — audit activity, waivers, bankruptcy, and others — that differ from civil litigation tolling rules. A statement that the limitations period has run in a tax context requires verification against the specific statutory provisions governing that type of tax and that type of period.
The phrase also appears in tolling analysis. Courts often ask whether the statute "ran" during a period of disability, minority, absence, fraudulent concealment, or pending litigation. In these contexts, the running is treated as interruptible, and the metaphor becomes important: time that has already run does not re-run after tolling ends, it simply resumes.
Researchers should also watch for the passive construction "the statute was tolled" paired with "the statute had already run" — a combination that signals a factual dispute about sequence and timing, often dispositive in the underlying case.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) — Supplemental defines the phrase concisely as "a metaphorical expression, by which is meant that the time mentioned in the statute of limitations is considered as passing," citing Bouvier's Institutes. This is an accurate characterization of what remains true today: the phrase is frankly metaphorical, borrowed from the idea of time flowing or a clock operating. Bouvier's treatment, from which Black's draws here, reflects the nineteenth-century understanding that limitations were creatures of statute to be interpreted narrowly, with the "running" beginning from the moment the right of action first arose — an accrual rule more rigid than modern discovery-based approaches.
What the historical sources do not address is the rich body of tolling doctrine that grew up around the running concept. Neither Black's second edition nor the Bouvier passage it cites engages with fraudulent concealment tolling, the discovery rule, or statutory tolling for minority and disability in any systematic way. Researchers using this phrase as an entry point into historical legal sources should treat the dictionary definition as a starting point only — the substantive law governing when running begins, pauses, and ends requires consulting treatises and case law contemporaneous with the jurisdiction and period under examination.

Jurisdictional Note
While every U.S. jurisdiction uses the concept of running of the statute of limitations, accrual rules and tolling doctrines vary substantially. Federal courts apply state limitations periods for state-law claims but apply federal accrual rules in some contexts. Tax limitations periods under federal law operate independently of state civil limitations frameworks.
