Definition
A fixed point in the Roman calendar used historically to reckon dates in legal instruments, records, and documents governed by Roman dating conventions. The Nones fell on the fifth day of most months, but on the seventh day of March, May, July, and October. The term derives from the Latin nonus (ninth), because the Nones were counted as nine days before the Ides of the same month under the Roman inclusive-counting method — that is, both the Nones and the Ides were counted in the interval.
In legal and historical research, Nones functions as a calendrical marker. A document dated "the Nones of March" places an event on March 7; "the Nones of June" places it on June 5. Dates expressed in Roman calendar form appear regularly in medieval charters, ecclesiastical records, canon law documents, and early English legal instruments.
Common Language
Modern common usage (Wiktionary): Nones carries several senses in modern English — the Roman calendrical marker described above; the ninth hour after dawn (approximately 3 p.m.); the divine office appointed to that hour in the Roman Catholic liturgical tradition; and, through later shift, a synonym for noon (midday) or a light meal eaten around that time.
Historical common usage (Webster's 1913): Webster's identifies Nones as the fifth day of most months and the seventh of March, May, July, and October under the Roman system, nine days before the Ides by inclusive count. It also records the canonical office of the Roman Catholic Church, originally recited at the ninth hour (3 p.m.) and later shifted to noon.
The legal meaning is the calendrical one — specifically the Roman calendar function used to anchor dates in primary sources. The liturgical and midday senses, while historically related (the canonical "None" migrated from the ninth hour to noon, giving English the word "noon"), are irrelevant to legal dating but may confuse researchers who encounter Nones in the context of ecclesiastical records where both senses could theoretically appear in the same document.
Common Confusion
Nones, Ides, and Kalends are the three fixed points of the Roman month, and all three appear in historical legal documents. The Kalends fell on the first day of every month. The Nones fell on the 5th (most months) or 7th (March, May, July, October). The Ides fell on the 13th (most months) or 15th (March, May, July, October). Days before each fixed point were counted backward inclusively: "three days before the Nones of April" is April 3, not April 2. Failure to apply inclusive counting is the most common error researchers make when converting Roman calendar dates to modern equivalents.
Why It Matters in Research
Researchers encounter Nones primarily when working with pre-modern primary sources — medieval English charters, ecclesiastical court records, papal documents, Roman law texts, and early modern instruments drafted in jurisdictions that retained Roman dating conventions. The term has no operative function in modern common law practice; its research value is purely interpretive and dating-specific.
The principal trap is the inclusive-counting rule. Researchers accustomed to modern exclusive counting (where "three days before" an event means subtract three) will systematically misdate Roman calendar references by one day. Every Roman backward-count includes both the terminal fixed point and the starting day. A secondary trap is the month-specific rule: Nones falls on the 7th only in March, May, July, and October — the four months that originally had 31 days in early Roman reckoning. All other months use the 5th. Applying the wrong date for the Nones in a given month produces a two-day error in conversion.
Burrill's citation to Adams's Roman Antiquities (Adam's Rom. Ant. 355, 357) identifies a standard reference work that researchers tracing the original scholarly apparatus behind these historical dictionary entries may wish to locate. Black's two editions agree on the core definition with no meaningful variation between them.
For Law Mind corpus research, Nones is most likely to appear in: canon law materials, where the Roman calendar persisted in ecclesiastical usage long after it faded from secular instruments; Year Books and early English plea rolls, which sometimes preserved Roman date-forms; and records touching on Roman law directly (civil law treatises, Scottish and continental sources). The term will not appear as a substantive legal concept with doctrinal content — it is a date marker, not a legal standard.
Historical Dictionary Support
All three historical sources consulted agree on the core definition without meaningful variation: Nones is the fifth day of most months, the seventh day of March, May, July, and October, and the name derives from the nine-day inclusive count to the Ides. Burrill's is the most complete entry, supplying the Latin derivation (nonus, ninth) and the citation to Adams. Black's first and second editions track Burrill's closely with minor typographical differences (the second edition's "mouth" for "month" is a printing error).
None of the three historical sources address the liturgical or noon-related senses of the term, which is appropriate — those senses are irrelevant to legal usage. None address the inclusive-counting mechanics explicitly, which is a gap, since that is precisely the information a researcher needs to convert a Roman date correctly. Researchers should not rely solely on these dictionary entries to perform calendar conversions; a Roman antiquities reference or classical dating guide is required for that purpose.
Jurisdictional Note
Nones as a dating convention is not a concept of any modern jurisdiction. Its relevance is historical and cross-jurisdictional: it appears wherever Roman calendar conventions were used, including Roman civil law systems, medieval canon law, and early English practice. Scottish legal records and continental civil law materials are more likely to retain Roman dating forms into the early modern period than English common law sources.
