Hi Sandra, For between dates, we have https://www.wikidata.org/wiki/Property:P1319 (earliest date) and https://www.wikidata.org/wiki/Property:P1326 (latest date) as qualifiers. You can set the claim itself on century or whatever then. You can also use P1326 for before dates, I think. Seasons is another thing, I think we need a new property for that. Same for quarters. But I agree, it should be great if this was integrated more. Showing better suggestions before saving is another thing that could help.

Many artworks (and, I assume, many other things) are dated in the following ways: 1. 'between 1850 and 1899’ - on Wikidata that could be ’18. century’ (yep, needs to be written like that) with qualifiers start date and end date ? 2. ‘between 1784 and 1787’ - on Wikidata ‘1780s’ with qualifiers? 3. ‘between 1878 and 1904 - on Wikidata... eeeehm? I was wondering: can’t we express this without needing any qualifiers at all? We can enter units as ‘320 cm plus/minus 7 cm’, right? Might we also be able to say ‘1898 plus/minus six years’? I can imagine we’d then also have an interface that helps you enter a ‘between date x and date y’ elegantly without needing to do any math. Or would that not be possible? I think it would be great to have, as it would make our dating conceptually much more accurate IMO. Curious what others think. Best, Sandra (User:Spinster) p.s. On Commons we have an {{Other date}} template that’s used very frequently, that allows rich time/date expressions, and that I really love. Here’s the documentation: https://commons.wikimedia.org/wiki/Template:Other_date Besides this ‘between’ concept, it also has, among other things * before (date) or after (date) - also very common! * seasons - you can say ‘Spring 1986’ * first/last half/quarter (year, decade, century) etc Some might not be translatable to a period as I suggested above, but some may. _______________________________________________ Wikidata mailing list Wikidata(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata _______________________________________________ Wikidata mailing list Wikidata(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata
