23041990

23041990 is an eight-digit sequence that commonly represents the calendar date 23 April 1990 when read in the day-month-year format. In regions and systems that adopt DDMMYYYY, the string corresponds to 23 April 1990, while other interpretations can lead to ambiguity without separators or a confirmed convention. The format is used in file names, databases, billing numbers, and other identifiers where a compact, sortable date key is advantageous.

As a date representation, 23041990 can be parsed into day = 23, month = 04, and year = 1990. In computing, such compact date strings are often stored as strings to preserve formatting or converted into a numerical timestamp for comparison. The same eight-digit sequence, if stripped of separators, is not universally meaningful outside a pre-agreed convention; for example, in the US MMDDYYYY format it would not be a valid representation.

There is no widely recognized historical event strictly associated with the date 23 April 1990; any significance would be local or contextual to regional calendars or news coverage. In other uses, 23041990 may appear as an arbitrary identifier, code, or part number in product inventories or archival systems.
