The standard does not assign any specific meaning to elements of the date/time to be represented; the meaning will depend on the context of its use.

In addition, dates and times to be represented cannot include words with no specified numerical meaning in the standard (e.g., names of years in the Chinese calendar) or that do not use characters (e.g., images, sounds).

In representations for interchange, dates and times are arranged so the largest temporal term (the year) is placed to the left and each successively smaller term is placed to the right of the previous term.

Representations must be written in a combination of Arabic numerals and certain characters (such as "-", ":", "W", and "Z") that are given specific meanings within the standard; the implication is that some commonplace ways of writing parts of dates, such as "January" or "Thursday", are not allowed in interchange representations.

The first edition of the ISO 8601 standard was published as ISO 8688 in 1988.

It unified and replaced a number of older ISO standards on various aspects of date and time notation: ISO 2014, ISO 2015, ISO 2711, ISO 3307, and ISO 4031.ISO 8601 fixes a reference calendar date to the Gregorian calendar of as the date the Convention du Mètre (Metre Convention) was signed in Paris.However, ISO calendar dates before the Convention are still compatible with the Gregorian calendar all the way back to the official introduction of the Gregorian calendar on .Earlier dates, in the proleptic Gregorian calendar, may be used by mutual agreement of the partners exchanging information.The standard states that every date must be consecutive, so usage of the Julian calendar would be contrary to the standard (because at the switchover date, the dates would not be consecutive).ISO 8601 prescribes, as a minimum, a four-digit year [YYYY] to avoid the year 2000 problem.
