19221999

19221999 is a four-digit string produced by joining the year numbers 1922 and 1999. In itself it carries no universally accepted meaning, but it can appear in various contexts as a compact identifier, a mistaken or informal representation, or a shorthand for a year range.

As a life span or period indicator, the conventional way to express a range is with a separator, such as 1922–1999, which would indicate someone born in 1922 and who died in 1999, or a historical span covering those years. The unpunctuated form 19221999 is ambiguous without additional context and may be read as a range, a concatenated key, or a catalog identifier rather than a precise date.

In data and information management, 19221999 can occur as a key or code in databases, inventories, or file names. Such concatenated year strings can simplify storage but require metadata or delimiting conventions to prevent misinterpretation. When encountered in a dataset, it is common to look for accompanying fields (for example birth and death years, or a separate separator) to determine the intended meaning.

Overall, 19221999 is not a standard historical notation. Its interpretation depends on context, and proper parsing typically depends on delimiters, metadata, or accompanying documentation to distinguish between a year range, a lifespan, or an identifier in a collection.
