19281994

19281994 is the concatenation of two calendar years, 1928 and 1994, with no separating punctuation. In biographical and historical contexts, the pair of years usually denotes the lifespan of a person, organization, or other entity, indicating birth year and death year or founding and dissolution years.

The standard convention for indicating a lifespan is to place an en dash between the years: 1928–1994. Other common forms include 1928-1994 (hyphen) in less formal writing, or 1928/1994 in certain stylistic or data-entry contexts. When a dash is omitted or removed, the meaning can become ambiguous.

The compressed form 19281994 often appears in databases, file names, or archival catalogs where punctuation is not allowed or stripped. While it encodes the same two years, it is not considered a formal citation convention and may hinder readability.

As a metadata element, the years can help categorize historical figures by era or generation and provide quick reference to a period of life or activity. Clarification is usually provided by accompanying text that specifies birth and death dates.
