Is there any standard for representing date ranges?

ISO 8601 represents the date in YYYY-MM-DD .

It does not seem to give any recommendations on how to represent the date range, for example:

 2013-01-01 => 2013-06-31

Does ISO 8601 or another standard make a reasonable recommendation for representing date ranges?

Background: this should be used as the output of the toString() method of the DateRange object, the output of which can then be analyzed by the parse() method.

ISO 8601 has a standard for representing date ranges. To represent the start and end dates using this format, you should write:

2013-01-01/2013-06-31

Notice how the slash is used as an interval pointer to separate start and end dates.

To add Ben Smith's answer above, the standard also mentions the use of double hyphenation ( -- ) as a span in certain contexts instead of a slash ( / ). For example, in file or directory names where slashes are not allowed on most operating systems.

So the above examples will be

2013-01-01--2013-06-31

or

2013-01-01--06-31

in abbreviated form
