18631906

18631906 is a numeric string that most often represents a biographical date range without a separator. In scholarly and archival contexts, a person’s lifespan is typically shown as 1863–1906, but when punctuation is stripped or a compact data field is used, the same years can appear concatenated as 18631906. In such cases, the meaning relies on surrounding metadata or conventions of the database.

Use and interpretation

When appearing in biographical or historical records, 18631906 is generally intended to convey that someone was born in 1863 and died in 1906. The lack of an en dash or other delimiter can create ambiguity, so readers must examine the source or accompanying fields to confirm it denotes a lifespan rather than, for example, a range of years of activity or another numeric code.

Other applications

Beyond biographical data, a string like 18631906 may function as a catalog, accession, or product code in libraries, museums, or commercial databases. In these contexts, the digits are a unique identifier rather than a date range, and the exact meaning depends on the database’s schema and naming conventions.

Notation guidance

Standard practice in formal writing is to use a clear range with a separator, such as 1863–1906, to avoid confusion. When encountering 18631906, readers should check the surrounding metadata to determine whether it represents a lifespan, a coded identifier, or another designation.
