19182015

19182015 is an eight-digit numeric string formed by concatenating two four-digit year values, 1918 and 2015. As a standalone label, it does not denote a widely recognized event, organization, or standardized designation.

In practical usage, such strings appear in data management, archival indexing, or file naming schemes where year markers are combined without separators. The sequence can be read in two common ways: as a simple concatenation of 1918 and 2015, or as an indicator of a date range spanning the two years, depending on the surrounding metadata.

Because there is no universal convention for such identifiers, interpretation relies on context. It may appear in catalog records to signal documents, datasets, or projects related to or spanning the years 1918 and 2015, or it may be used as a unique identifier in a database or library system.

Limitations include ambiguity and potential confusion when read outside of its intended context. Without accompanying metadata, 19182015 conveys little by itself beyond the two embedded years.
