Will people know when I ve updated information on Facebook?

Today is my birthday and I just realized that its private on Facebook to only me. Now this is narcissistic, but I want to change who can see my birthday so that all my friends will see. I know how to do this, but my question is - if I update my info, will people see that I ve updated it? Like will it come in their timeline saying "so and so changed blah blah blah" like it does sometimes when people add a school or something. I don t want to make it obvious that I m changing the info so people can see its my birthday. Don t judge please.
