I also found out that if you keep jumping back and fourth 8-15 days you'll get a good amount of campsite villagers too! (for example, May 1st to May 15th then back to May 1st and so on)
I was attempting to kick someone out for an empty plot, and I jumped from april 24th (the current day I did it on) to may 8th back and forth several times, and got so many campsite villagers (though since I wasn't actually trying to get campsite villagers, I didn't pay much attention to the stats)
I wanted to do this again because I've been searching for Rudy and Punchy. But the farthest I've reached was June 14, 2022. I really don't want to continue that far because I've returned to the current date after I finally had Elvis.
So, I just want to confirm and clarify... does that mean I can just do May 1 to May 15 infinitely?
I might be repeating what you just said, but my brain is not digesting info properly right now.
