19011984

19011984 is an eight-digit numeric string used to encode a calendar date. In the day–month–year convention common in many countries, 19 January 1984 is written as 19011984. In ISO 8601, the same date is written as 1984-01-19. As a compact date stamp, it is sometimes employed in file names, database keys, archival identifiers, or other metadata fields where a fixed-width numeric representation is desirable.

Because the string encodes a date rather than a specific event, 19011984 does not refer to a single historical incident. It may appear in historical records by date or in systems that index material by date. The lack of separators means it can be ambiguous if presented without context.

Ambiguity is a salient issue with eight-digit date forms. Without locale information, digits could be read as either DDMMYYYY or MMDDYYYY in different regions. This has led to recommendations to use unambiguous formats such as ISO 8601 (YYYY-MM-DD) or to insert separators to clarify the intended order of day and month.
