Motivation[edit]

It would help modeling the translation/conversion of dates from a gregorian date to another calendar date. In other words, would be alike said to be the same as (P460) but only for different calendar dates. Bouzinac (talk) 21:55, 18 June 2020 (UTC)

Discussion[edit]

  • Please format the examples in the way we usually format the examples in property proposal instead of using language like "would welcome" which is unclear about how exactly the content is supposed to be modeled. ChristianKl❫ 10:11, 19 June 2020 (UTC)
Hello ChristianKl (talkcontribslogs), hope the examples are clearer for you. Sincerely Bouzinac (talk) 13:03, 19 June 2020 (UTC)

  • Symbol oppose vote.svg Oppose I can see that we do have items for different recent dates because wikinews are organized per day, but why we we need the same day expressed in different calendars? Just use aliases. --Jarekt (talk) 02:37, 20 June 2020 (UTC)
With the aliases system, you cannot query what was the date xx/xx/xxxx in other calendar than gregorian. I just wish there is a way to query that the point in time (P585) for Storming of the Bastille (Q6539) was in xx/xx/xxxx for Jewish calendar, for instance. Wikidata should be transcultural. There may be variation of dates among calendar and each date is a single item (that date in muslim calendar was in month XX, was a muslim Saturday, etc.). Perhaps a property single text per calendar would be more feasible (property for iranian calendar, property for jewish calendar etc). Bouzinac (talk) 10:41, 20 June 2020 (UTC)
  • Symbol oppose vote.svg Oppose I don't think the current construction is desireable. Maybe we need:
20 July 2012 (Q17982050) month of the year (P2922) July (Q121) ?applies? Gregorian calendar (Q12138)
20 July 2012 (Q17982050) month of the year (P2922) Sivan (Q2291025) ?applies? Hebrew calendar (Q44722)
Then we could have similar properties to month of the year (P2922) for the other parts of a date as well. I'm not sure that applies to part, aspect, or form (P518) does the job. Applies in context might be better. ChristianKl❫ 11:10, 20 June 2020 (UTC)
