20050419

20050419 is a numeric date string that uses the YYYYMMDD format. In the Gregorian calendar it represents April 19, 2005. In ISO 8601 notation, the same moment is written as 2005-04-19. The eight-digit form is commonly used in computing and data management because it sorts in chronological order when treated as a string or number and it avoids regional ambiguities between day-month and month-day formats.

Common uses include naming files and folders, labeling data backups, timestamping log entries, and serving as keys in archival catalogs or batch processes. It may be extended with a time component to form more precise timestamps (for example 20050419T153000 for 3:00 PM). In practice, 20050419 often appears in systems that require stable, sortable date identifiers without punctuation.

Contextual interpretation can differ in non-Gregorian calendars, but the Gregorian date is the standard in most international data contexts. The date itself is the 109th day of 2005, and there is no leap-day impact on this date.

As with any date string, its significance depends on the domain. There is no single globally recognized event universally tied to 20050419; rather, it functions as a marker that may coexist with separate historical records in different regions or industries.
