When dates are represented with numbers they can be interpreted in different ways.
Fortunately, there is one solution in the ISO-developed international date format.
The purpose of this standard is to provide an unambiguous and well-defined method of representing dates and times, so as to avoid misinterpretation of numeric representations of dates and times, particularly when data are transferred between countries with different conventions for writing numeric dates and times.
In general, ISO 8601 applies to representations and formats of dates in the Gregorian (and potentially proleptic Gregorian) calendar, of times based on the 24-hour timekeeping system (with optional UTC offset), of time intervals, and combinations thereof.
The worst potential usability problems come when the date is written only with numbers as in the following example, because the date's interpretation will be different from one country to another. Note that this format can also be used to represent precise date and time, with timezone information Using numerical dates does have also some pitfalls with regard to readability and usability, as explained in the Date formats The W3C QA Tips are short documents explaining useful bits of knowledge for Web developers or designers, hosted and produced by the Quality Assurance Interest Group at W3C.
