19091972

19091972 is a numeric string that can denote a calendar date in day-month-year order when written without separators. Interpreted as 19 September 1972, it corresponds to the 262nd day of the year in the Gregorian calendar, with 1972 being a leap year. The eight-digit format is commonly used in some regions and in data records where separators are inconvenient or standardized for sorting.

However, as a bare sequence of digits, 19091972 is ambiguous outside of a specified format. In systems employing different date conventions, such as month-day-year, or in purely numeric identifiers, the same string could be read differently or serve as an identifier rather than a date.

In archives, libraries, and digital datasets, compact eight-digit dates are used for file naming, catalog numbers, or metadata keys. A file named 19091972 would often be understood as created or relevant to that date under a ddmmyyyy scheme, but confirmation from accompanying metadata is required to avoid misinterpretation. The string also appears in non-date contexts as a potential code or label.

There is no widely cited event universally tied to the exact date in standard references. As with any historical date, the significance of 19 September 1972 depends on regional history, project scope, or archival conventions.
