Definition
Pertaining to the Lord's Day, or Sunday. In legal contexts, "dominical" appears primarily as a descriptor identifying Sunday — typically in statutes, religious law, ecclesiastical records, and historical documents that regulate activities on the Sabbath or calculate ecclesiastical dates tied to Sunday observance. The term does not carry independent legal force as a standalone doctrine; it functions as a qualifying adjective within the frameworks of Sunday laws (blue laws), ecclesiastical law, and calendar-based legal calculations.

Common Language
Modern common usage (Wiktionary): "Of or pertaining to Jesus Christ as Lord; of or pertaining to the Lord's Day, Sunday; of or pertaining to the ancient system of dominical letters used for determining Sundays (particularly Easter Sunday) in any given year."
Historical common usage (Webster's 1913): "Indicating, or pertaining to, the Lord's day, or Sunday. Relating to, or given by, our Lord; as, the dominical (or Lord's) prayer. Dominical letter: the letter which, in almanacs, denotes Sunday, or the Lord's day."
The legal meaning does not diverge sharply from common usage, but the practical legal application is narrower. In ordinary and ecclesiastical usage, "dominical" can refer broadly to anything related to Christ as Lord, the Lord's Prayer, or the system of dominical letters used in calendar computation. In legal sources, the term is almost exclusively confined to its Sunday-identification function — appearing in contexts where the Lord's Day has legal significance, such as Sunday trading restrictions, Sabbatarian legislation, or ecclesiastical court documents.

Why It Matters in Research
Researchers will encounter "dominical" primarily in three legal-historical contexts, and the term is rarely the subject of independent legal analysis.
First, Sunday laws and Sabbatarian legislation: Historical statutes restricting commerce, labor, or legal proceedings on Sunday sometimes use "dominical" as a formal descriptor for the Lord's Day. Tracing such laws in the Law Mind corpus requires recognizing the term as a synonym for Sunday in archaic statutory drafting.
Second, ecclesiastical and canon law sources: Dominical letters — the seven letters A through G assigned cyclically to January 1 through 7 and used to identify which day of the week is Sunday in a given year — appear in ecclesiastical legal records to fix liturgical dates, calculate the date of Easter, and determine the timing of obligations under church law. Documents from English ecclesiastical courts, probate records tied to feast-day deadlines, and church property instruments may use this system. Researchers unfamiliar with dominical letters may misread date references in pre-modern ecclesiastical records.
Third, civil date calculations with religious anchors: In historical English and colonial American legal practice, certain legal deadlines and property rights were expressed by reference to feast days or Sundays. Understanding dominical letter calculations can be essential to determining the precise calendar date intended by such instruments.
The term is essentially extinct in modern statutory and judicial drafting. Its appearance in a legal document is a reliable marker of historical or ecclesiastical source material.

Historical Dictionary Support
Black's Law Dictionary (1st Ed.), Rapalje & Lawrence, and Black's Law Dictionary (2nd Ed.) are in complete agreement: all three define "dominical" identically as "that which denotes the Lord's day, or Sunday." No variation, expansion, or contradiction exists across these sources.
The convergence is unsurprising given the term's narrow application, but it also reflects the limits of historical legal dictionary treatment. None of the three sources addresses dominical letters as a calendar-computation system or explains how the term functions in ecclesiastical date-reckoning — a gap that matters when the researcher encounters the term in ecclesiastical court records or pre-modern instruments that fix obligations by reference to Sundays in a liturgical calendar. Webster's 1913 provides more practical detail on this dimension than any of the legal dictionaries do.

Jurisdictional Note
Dominical appears most frequently in English ecclesiastical law sources and in American statutes and cases from jurisdictions that maintained robust Sunday-closing legislation into the twentieth century. Its relevance in modern U.S. jurisdictions is largely historical; most Sunday law frameworks have been repealed or are rarely enforced, and contemporary legal documents do not use the term.
