Definition
A Christian feast day observed on January 6th, the twelfth day after Christmas, commemorating the manifestation of Christ to the Gentiles as represented by the visit of the Magi to the infant Jesus. Also called Twelfth Day. In legal contexts, Epiphany appears not as a doctrinal concept but as a calendar marker — relevant to the computation of time, the observance of court terms, the enforcement of contracts, and the operation of ecclesiastical law in jurisdictions where religious feast days carried legal significance.
Common Language
Modern common usage (Wiktionary): An illuminating realization or discovery, often resulting in a personal feeling of elation, awe, or wonder; also, a manifestation or appearance of a divine or superhuman being.
Historical common usage (Webster's 1913): A church festival celebrated on the 6th of January, the twelfth day after Christmas, in commemoration of the visit of the Magi to Bethlehem; also used more broadly to mean any appearance or becoming manifest.
The common modern meaning — a sudden personal revelation — is entirely absent from the legal record. When Epiphany appears in legal sources, it functions solely as a fixed calendar date. Researchers encountering the term in historical legal documents should not import the contemporary figurative sense; the legal usage is purely temporal and liturgical.
Why It Matters in Research
Epiphany enters the legal corpus almost exclusively through two channels: ecclesiastical law and the historical calendar of court terms and legal holidays.
In English law and the law of jurisdictions shaped by it, certain court terms were organized around the liturgical calendar. Hilary Term — one of the four traditional terms of the English common law courts — began shortly after Epiphany and was sometimes referred to in older sources by reference to the feast itself. Researchers working with pre-Judicature Act English materials, or with early American court records that preserved English term structures, should recognize Epiphany as a temporal anchor for Hilary Term and be alert to date calculations built around it.
In civil law and ecclesiastical law traditions, feast days including Epiphany could affect the running of time periods, the validity of certain acts performed on dies festi (feast days), and obligations under ecclesiastical courts. Continental European legal systems, canon law materials, and the law of jurisdictions with strong civil law heritage (Louisiana, Quebec, historically Catholic colonial territories) may reflect these observances more directly than common law sources.
The term also appears in historical contract and commercial law when parties specified performance dates by reference to feast days rather than calendar dates — a practice common in medieval and early modern instruments that persisted in some agricultural and ecclesiastical lease forms well into the nineteenth century. A researcher encountering a lease requiring rent "at Epiphany" must translate that to January 6th and then assess whether local rules about feast days, Sundays, or non-judicial days affect the computation.
The Rapalje & Lawrence entry is notable for its editorial placement: the definition of Epiphany appears immediately following a reference to expressio unius est exclusio alterius, with no logical connection — a reminder that historical legal dictionaries were often arranged with imperfect alphabetical or thematic discipline, and that surrounding entries do not reliably illuminate meaning.
Historical Dictionary Support
Black's Law Dictionary (both the first and second editions) and Rapalje & Lawrence are in complete agreement: Epiphany is the Christian festival of January 6th, the Manifestation of Christ to the Gentiles, commonly called Twelfth Day. All three sources cite the Encyclopaedia Londinensis as authority, suggesting the entry migrated substantially unchanged across editions and compilers rather than reflecting independent legal analysis.
What the historical dictionaries do not address is why the term appears in a law dictionary at all beyond bare identification. None of the sources explains the operational legal significance — the feast day's role in term-time calculations, dies non juridicius questions, or ecclesiastical court practice. For that context, researchers must look beyond the dictionary shelf to primary sources on court terms, ecclesiastical law treatises, and historical legal calendars.
Jurisdictional Note
Epiphany retains practical legal significance primarily in jurisdictions with strong ecclesiastical law traditions or civil law heritage. In Louisiana, certain traditional feast days have had recognized legal status. In England, the historical relevance is largely historical following the Judicature Acts and subsequent court reforms. In most common law American jurisdictions, the term is a historical artifact with no operative legal effect.
