What is xxiv?

XXIV is a Roman numeral representing the number 24. In Roman numerals, X is equivalent to 10, and IV is equivalent to 4, so when combined, XXIV equals 24. Roman numerals were commonly used in ancient Rome for numbering and counting. They are still used today in certain situations, such as indicating the sequel number of a movie or the year in some formal documents.

In addition, XXIV can also refer to an event or organization named "XXIV," but without further context, it is unclear what specific event or organization is being referred to.
