Full Title

ISO 8601, Data Elements and Interchange Formats - Information Interchange - Representation of Dates and Times


ISO 8601 enables exchange of data relating to dates and times of day by providing specifications for alphanumeric and character representations of these. It also provides formats for these representations. The specification makes it possible to create a unique representation of any date or time expression including: calendar dates, ordinal dates, week numbers, time intervals, recurring time intervals, combined date and time of day, and differences between local time and Coordinated Universal Time.
