ISO 8601

The International Standards Organisation's standard, number 8601 is an international standard for date and time representations. It is used for all date-time representations in microformats.

Overview

For a plain-language overview of ISO 8601, we recommend the ISO 8601 summary by Markus Kuhn.

Microformats

Microformats using ISO8601 include:

RFC 3339

RFC 3339 defines a profile of ISO 8601 for the use in Internet protocols and standards.

  • It explicitly excludes durations and dates before the common era.
  • The more complex formats like week numbers and ordinal day are not permitted (see RFC 3339, section 5.6).

Microformats SHOULD use RFC 3339.

Issues

  • Should we restrict microformats' use of ISO 8601 to RFC 3339 values? Andy Mabbett
  • How should dates before the common era be marked up? Andy Mabbett
