Definition
In law, a date is the specification of time — typically day, month, and year — attached to a written instrument, and it carries a meaning more precise and consequential than the word's ordinary usage suggests.
Three distinct but related concepts travel under the same term:
1. The date as written: The time specified within the instrument itself — the date as it appears on the face of a deed, contract, or other writing. This is the primary legal meaning. Historical sources are consistent: the date of an instrument is not simply when something happened, but the time formally given or assigned within the document.
2. The actual date: The time when an instrument was actually made, acknowledged, delivered, or recorded — which may differ from the date written on its face. Courts have long recognized that these do not always coincide, and the discrepancy carries legal consequences depending on the type of document and the applicable rule.
3. The operative date: The time from which an instrument's legal operation is reckoned — which may be the written date, the delivery date, or some other anchor depending on the legal context. Statutes of limitations, priority disputes, vesting of rights, and benefit entitlements all depend on identifying which date governs.

Common Language
Modern common usage (Wiktionary): A specific day in time at which a transaction or event takes place, or is appointed to take place; also the time specification added to a writing indicating when it was given or executed.
Historical common usage (Webster's 1913): Webster's 1913 treats "date" primarily as the fruit of the date palm, reflecting that "date" as a time-marker was so thoroughly absorbed into ordinary use that the dictionary defaulted to the less obvious meaning. The time-specification sense was already conventional English by 1913.
The gap worth noting: In ordinary usage, "the date of" something simply means when it happened. In legal usage, the date of a document is a formal designation that may control legal rights independent of when underlying events actually occurred. Researchers reading instruments must ask not just what date appears, but what legal effect that date carries — and whether the written date, delivery date, or recording date is the operative one for the question at hand.

Common Confusion
Three dates frequently diverge in practice and are frequently conflated in both instruments and legal argument:
- Date of execution: When the instrument was signed.
- Date of delivery: When the instrument passed from grantor to grantee, which in most conveyancing traditions is when the deed takes legal effect.
- Date of recording: When the instrument was entered in the public record, which governs priority against subsequent purchasers under most recording acts.
In addition, statutory schemes — veterans' benefits, insurance coverage, matrimonial property — often impose their own defined "operative date" that overrides all of the above. Researchers must identify which date concept the applicable legal framework is using before applying any rule.

Why It Matters in Research
Date is one of the most deceptively simple terms in the legal corpus. It appears in nearly every written instrument, but its operative meaning varies across document types, legal frameworks, and historical periods — and errors in identifying the controlling date are a recurring source of litigation.
In historical sources, the date of a deed was the datum clause — literally the "given" clause specifying place and time — and it carried formal significance in conveyancing that has eroded in modern practice. Researchers working with historical deeds, particularly those predating standardized forms, should recognize that the absence of a date, or a date that conflicts with other evidence, was a recognized legal problem addressed by rules of construction. Anderson's Dictionary flags that the date governs the time from which an instrument's operation is reckoned — a principle that survives but is now embedded in doctrine rather than expressed on the face of modern instruments.
In benefits and entitlements research (particularly veterans' law), "date of claim" and "date of entitlement" are terms of art with statutory definitions that do not map neatly onto either the date an event occurred or the date a document was signed. Retroactive effect, clear and unmistakable error corrections, and accrued benefits all hinge on date determinations governed by specialized regulatory frameworks.
In insurance research, retroactive dates and extended reporting periods create coverage windows that are entirely date-defined. The "date" of an occurrence, a claim, or a policy period can determine whether any coverage exists at all — and these are distinct concepts under occurrence-based versus claims-made policies.
In family law, the date of valuation for marital property can be the date of separation, the date of filing, or the date of trial, depending on jurisdiction and asset type. The choice of valuation date can dramatically affect the distribution outcome.
Researchers using older dictionaries should note that historical sources universally define date as the time specified in the instrument — emphasizing the formal, written designation. Modern legal practice increasingly asks courts to look behind the written date to the actual operative event, which those historical sources treat as a secondary (though recognized) concern.

Historical Dictionary Support
The historical dictionaries converge on a single core proposition: the legal date of an instrument is the time formally given or specified within it — not an abstract or reconstructed time, but a designated one. Black's (both editions) and Bouvier's agree that this is the primary signification, grounded in the Latin datus (given). Burrill traces the term's formation explicitly to the datum clause of ancient deeds, where the place and time of giving were stated together.
Anderson's adds useful nuance by identifying the multiple temporal reference points an instrument can carry — time of making, acknowledgment, delivery, or recording — and noting that the date clause serves to fix the operative one. This is the most practically useful formulation for a researcher, because it captures what courts actually have to resolve when dates conflict.
What the historical sources do not address: statutory date definitions (which are a creature of modern administrative law), the claims-made/occurrence distinction in insurance, and any of the specialized date concepts that pervade benefits law. Researchers should treat the historical dictionaries as authoritative for the common-law conveyancing context and as a starting point only for modern statutory and regulatory frameworks.

Jurisdictional Note
Jurisdictions vary on which date governs the legal effect of a deed — most U.S. jurisdictions treat delivery, not execution, as the operative moment, but recording acts layer additional date-based priority rules on top of that baseline. In insurance, whether the date of occurrence or the date of claim controls coverage is a policy-type question that varies by contract form and state regulation. Veterans' benefits date rules are federal and uniform in source, though adjudicative application varies.
