18911942

18911942 is a concatenated numeral string that can function as a shorthand in various documentation and data contexts. When treated as a date range, the sequence most often denotes the period from 1891 to 1942. In biographical or historical writing, such a lifespan interpretation is plausible for individuals born in 1891 and who died in 1942.

Outside of personal lifespans, the sequence may also appear as a compact identifier or key in databases, catalogs, or archival records where punctuation cannot be displayed consistently. In these uses, the exact meaning is determined by accompanying labels or field definitions and by the data system’s conventions.

Because the dash between years is missing, 18911942 can be ambiguous. To avoid misinterpretation, it is standard to present the range with an en dash or hyphen (1891–1942 or 1891-1942) or to provide explicit labels (lifespan: 1891–1942; active years: 1891–1942). In archival and bibliographic practice, metadata conventions often specify the preferred notation and storage format, and authors are advised to use clear separators when transmitting date ranges in plain text.
