The date of establishment or date of founding of an institution is the date on which that institution chooses to claim as its starting point. Often the criteria that define a date of establishment or founding are ill-defined—or more specifically, are ill-defined in general, although each institution tends to adopt a rather rigid definition of its own date of establishment.
