18951983

18951983 is a compact textual form used to indicate a lifespan from 1895 to 1983 when punctuation is omitted. In standard biographical notation the same range is written as 1895–1983, using an en dash. The unpunctuated form appears in plain text records, filenames, database keys, or OCR outputs where a dash or space may be lost.

Interpretation: The first four digits denote the birth year, and the last four denote the death year. Therefore, a subject associated with 18951983 is presumed to have been born in 1895 and died in 1983. When used in metadata, this information is typically tagged as a lifespan or years lived and can be used to filter or sort biographical entries.

Variations and limitations: Some datasets may replace the dash with a space or omit punctuation, producing forms like 1895 1983 or 18951983 without a clearly marked separator. In cases where the death year is unknown or the person is still living, different conventions apply, such as leaving the field incomplete or using separate birth and death fields in structured data.

Applications: The compact form is common in archival inventories, digitized catalogs, and file naming conventions where space is at a premium or where machine readability is prioritized. It requires contextual cues to avoid ambiguity and is typically interpreted by software as two distinct year values representing birth and death.
