19111984

19111984 is an eight-digit numeral that is commonly used as a compact date string in records and data systems that omit separators. In many European and other non-U.S. contexts, the sequence is interpreted as 19 November 1984 (DDMMYYYY). Interpreting the same digits as MMDDYYYY would not form a valid month, because the leading digits 19 do not constitute a legitimate month, which helps reduce some ambiguity in practice. The ISO 8601 standard writes this date as 1984-11-19, which clarifies the order of year, month, and day.

In the Gregorian calendar, 1984 was a leap year, so 19 November falls on the 324th day of the year. There are 42 days remaining in 1984 after 19 November. The date sits in the late autumn season for the northern hemisphere and is near the transition toward winter in many regions, with weather and daylight patterns typical of that period.

The numeric form 19111984 is widely used as a basic key in archival indexing, file naming, and bibliographic records where separators are impractical. Its meaning can depend on locale settings or data standards, which is why standardized representations such as 1984-11-19 are recommended for international data exchange to avoid misinterpretation.
