#1179: ISO 8601

ISO 8601

Public Service Announcement:

Our different ways of writing dates as numbers can lead to online confusion. That’s why in 1988 ISO set a global standard numeric date format.

This is the correct way to write numeric dates:

2013-02-27

The following formats are therefore discouraged:

02

27

2013 02

13 27
