Inexact dates and SPARQL

I am working on improving the information on Spanish on Wikidata as a personal project and learning exercise and I am confronted with Wikidata answering with 1900-01-01 for a 19. century date. See for example Q88271758 (Juan Llácer) born in the 19. century according to the Wikidata web rendition but if you check the SPARQL (https://query.wikidata.org/#SELECT%20%3Fp%20%3Fo%20WHERE%20%7B%0A%20%20wd%3AQ88271758%20%3Fp%20%3Fo%20.%0A%7D) it is presented as 1 January 1900. Taking into account that he died on 1855 I understand that this is an easy way to indicate that the birth date is kind of unknown but still, referring to the XIX century as 1900-01-01 is strange to me.

Display of century value in English

The example for showing a date as a century is Paraskeva of the Balkans (Q6967370). With the language set to English, her date of birth shows as "10. century", with a full stop in the German style (10. Jahrhundert). This is not correct in English, where the abbreviation is "10th century". If one changes the language to French it correctly shows as "10e siècle". How do we correct this display for century values?

Unfortunately I don’t think it’s possible to fix it in English right now. The French localization takes advantage of the fact that except for 1er, all ordinals end in e. In English, however, many numbers don’t have the th ending: 1st, 2nd, 3rd, 21st etc. This level of complexity cannot be expressed using the current localization system. It would be possible to change 10. century to Century 10, but I’m not sure if that would be better. —Tacsipacsi (talk) 09:13, 31 August 2023 (UTC)

Thanks for the reply. "10 century" would be slightly better as it's not-quite-right as opposed to "10. century" which is actively wrong. I agree that "Century 10" would be worse. Opera hat (talk) 17:28, 31 August 2023 (UTC)

circa vs near

"sourcing circumstances (P1480) qualification of the accuracy of a statement. Allowed values: circa (Q5727902), near (Q21818619), presumably (Q18122778), disputed (Q18912752), etc." - I think "near" should be removed from this section, because it is about locations, not about time.

Julian dates

Could someone explain how one enters a Julian (vs. Gregorian) date in the regular UI for an item? - Jmabel (talk) 00:06, 22 February 2024 (UTC)

I can try to. For example, here You chose date of birth, then push edit. You will see something like a table with his date of birth, accuracy and caledar. Push on "Gregorian calendar" then choose Julian and push on "keep". Ksc~ruwiki (talk) 19:47, 22 February 2024 (UTC)
