where are roman numerals used

Roman numerals are used in various everyday and specialized contexts today. Common uses include numbering chapters in books, marking hours on clock faces, and indicating the years of events such as the Olympics. They appear on buildings to show the year of construction and are frequently used in movie credits to denote production years. Additionally, Roman numerals designate monarchs, popes, and similar titles, and they are used in scientific fields like chemistry, astronomy, and seismology for specific notations. They also have military and legal uses, for instance, to label military units or organize legal codes. In music, they are used for chord analysis and movement numbering. Roman numerals thus continue to serve both decorative and functional roles in modern life across a variety of domains.
