Some people have proposed using ISO 8601 for Wikipedia dates. For more of this discussion, see Wikipedia talk:Manual of Style (dates and numbers).
- It appears that it's rapidly becoming a de facto standard (if not yet de jure) at least for dates in Wikipedia citations.
You can use quite a couple templates, in the YYYY-MM-DD date format
Removed bogus claims about hypen/minus differences.
I have removed this paragraph from the article:
→ISO 8601 permits the hyphen (-) to be used as the minus (−) character when the character set is limited. In contrast, RFC 3339 explicitly requires the hyphen (-) symbol to represent negative offsets and does not allow for use of the minus (−) symbol.
I don't know where this is from, but it's certainly not covered by the sources, and clearly wrong: ISO 8601 explicitly moves character encoding and character set out of scope, and mentions that ISO 646 maps both hyphen and minus to the same character (as does unicode btw.). To confuse things more, the character displayed in the article as the alleged "hyphen" depends on the browser, and might be a hyphen, minus, or minus-hyphen.
Similarly, RFC 3339, by using ABNF, specifies the hyphen-minus character, which stands for either the hyphen or minus.
Revised specification arrived: ISO 8601:2019
HH 24 hour times vs hh 12 hour times
Most systems I have worked with since 1995 designate 24 hour clock settings as 'HH' and 12 hour clock settings as 'hh,' to help differentiate the styles when adjusting system settings, but this article uses 'hh' as the 24 hour designation. Should this be changed? DocKrin (talk) 06:10, 4 May 2019 (UTC)
