200405

200405 is a six-digit string that can function as a date stamp, a code, or a label, depending on context. In date notation using the YYYYMM scheme, 200405 ordinarily denotes May 2004. This compact form is widely used in databases, financial systems, and archival repositories to preserve chronological order without separators.

Common uses include monthly period identifiers in accounting and reporting, file naming conventions, data set versioning, and log or batch identifiers in operations and manufacturing. It can also serve as a release date tag in software deployment, or as part of an internal catalog or inventory code where year and month convey timing information.

Interpreting 200405 requires context, and the same string may denote different things in different systems. If treated as a date, the year is 2004 and the month is 05 (May). Validation should ensure the month is in the 01–12 range. If used as a code, its meaning is defined by the issuing organization. Because the string is not unique to a single meaning, users should refer to the surrounding metadata or system documentation to determine its intended interpretation.
