DCCCXXVIII is the Roman numeral representation of the Arabic number eight hundred twenty‑eight. The numeral is composed of the symbols D for five hundred, CCC for three hundred, XX for twenty, and VIII for eight, which together sum to 828. The use of Roman numerals dates back to ancient Rome, where they were employed in inscriptions, dates, and numbering systems. The format of combining symbols from largest to smallest allows a compact representation, and DCCCXXVIII follows the traditional construction rules.

The number 828 itself appears in various historical and cultural contexts. In the calendar of the Christian era, the year 828 AD saw the reign of Emperor Louis the Pious in the Carolingian Empire and the ongoing consolidation of the early medieval European polities. In the Jewish calendar, 828 corresponds to the year 328 of the Hebrew era, marked by certain biblical events. The number also arises in modern contexts as a numeric identifier, such as a model number for industrial equipment, a highway designation, or a reference in legal codes.

In contemporary use, Roman numerals remain common for decorative purposes, such as numbering chapters in books, listing presidents in the United States, or labeling floors in high places. DCCCXXVIII may appear on clocks or monuments that aim for a classical aesthetic. In computing, the decimal number 828 translates to binary 1100111100 and hexadecimal 334. The numeral thus functions as a bridge between ancient symbolic systems and modern digital representation, illustrating the historical continuity of numeric notation.
