Inception date

Even though people celebrate October 29, 2012 as the inception data of Wikidata, I changed the date to October 25, 2012 on this wiki. Why? For consistency reasons: It is impossible to figure out the correct inception dates in retrospect other than checking for the first edit on the wiki. I believe this is the only date that can consistently be determined. Cheers --Kghbln (talk) 09:02, 16 September 2023 (UTC)

I think that is correct so far as we define inception date to be the date the wiki went online for the first time, ever. If revision 1 is dated to October 25 then that would be the inception date, even if the official "opening" was a few days later. Could we have both values as claims on the item, with one value qualified as the "observed" birthday? Harej (talk) 16:22, 17 September 2023 (UTC)

To additionally have an "observed" birthday makes sense. Not sure how to best name it. We will not be able to fill it in most cases, though. --Kghbln (talk) 16:26, 18 September 2023 (UTC)

Hmm, inception day and birthday as a pair could be good enough, I believe. --Kghbln (talk) 16:27, 18 September 2023 (UTC)

We probably also need a date defining when Wikibase started being used to the wiki. I can imagine a wiki that only added Wikibase and friends sometime after its inception and birthday. In this case, the date should be when they started using the software, i.e., the day the first item or property was created. This date can also be determined for every instance using Wikibase. If not they installed the software but never used it. Also good to know. --Kghbln (talk) 16:32, 18 September 2023 (UTC) PS Zetawiki Is a good example for the latter case.
