ca. (note the period) is not the same as CA; it is an abbreviation for circa. This redirect was set up originally, but for some reason changed to CA in 2021 by BD2412. In my opinion the original redirect was better. --Викидим (talk) 08:09, 29 March 2022 (UTC)
- Circa is not an article; it is a disambiguation page. I expect that the band, Circa, the company, Circa, the Peruvian Circa District, or the Circa Resort & Casino, are not referred to as "Ca.", so it would by incorrect to retarget the abbreviation to that disambiguation page. We have no article on "Circa" as a concept in the recording of dates. If we had such an article, the redirect would be appropriate to reconsider. BD2412 T 15:54, 29 March 2022 (UTC)
