I was looking through the Side Shot Saturday post and noticed the dates of the posts are off. Last weeks posts were dated Thursday June 18. Now I know COVID and quarantine has messed with my sense of time but I know the posts were made on Saturday. I went back and checked a few other threads and the same thing appears to be happening. Is there an issue with the calendar?

Everything looks good to me.

Mikey's right, if that doesn't work, try clearing you history and cache. My dates and times seems to to be correct for my time zone.
