Roman numerals are still used in many everyday and formal contexts, mainly for tradition, style, and clarity in ordering items.

Common everyday uses

  • Clock and watch faces, especially decorative or traditional ones, often label the hours I to XII.
  • Book front matter and chapters: introductions, prefaces, appendices, and sometimes chapter numbers (e.g., Chapter IV, Page xiii) use Roman numerals for hierarchy.
  • Outlines and lists in reports or legal documents sometimes use Roman numerals for topā€‘level headings (I, II, IIIā€¦).

Events, sports, and dates

  • Major recurring events like the Super Bowl and the Summer/Winter Olympics are often numbered with Roman numerals (e.g., Super Bowl LIV).
  • Important historical dates appear in Roman numerals on monuments, coins, and national symbols (for example, the U.S. Great Seal uses MDCCLXXVI for 1776).
  • Annual editions of events, awards, or conferences may use Roman numerals to emphasize tradition and prestige.

Names, titles, and generations

  • Monarchs and popes are commonly numbered with Roman numerals, such as Queen Elizabeth II or Pope John Paul II.
  • People in the same family line can use generational suffixes like John Smith III or IV.

Architecture, buildings, and signs

  • Cornerstones and facades of buildings often carry the construction year in Roman numerals.
  • Floor numbers or sections in some European buildings, and certain road or kilometer markers, still use Roman numerals.

Science, math, and tech

  • In mathematics and geometry, Roman numerals are used to label quadrants on the coordinate plane (Quadrant I, II, III, IV).
  • In science fields like chemistry and astronomy, they can mark groups or series, such as oxidation states or the numbering of planetary moons (e.g., Saturn VI for Titan).
  • Modern digital uses: app interfaces, video game sequels (e.g., Final Fantasy VII), and website branding sometimes prefer Roman numerals for stylistic numbering.

In short, when you see numbering that is supposed to look formal, historic, or ā€œspecial,ā€ thereā€™s a good chance Roman numerals are doing the job.

TL;DR: When people ask ā€œwhere are Roman numerals used,ā€ the answer today is: clocks, books, big sports events, monarch and pope names, building dates, some science labels, and stylish titles in media and branding.
