searching for a calendar/repeating post plugin

hello, im working on a specific section for my wordpress page and i’m looking a certain plugin that does the work. i tried a few of the top search-resulted ones but they didn’t get the job done.

i need it to do the following:

say i have a regular entry with title and content. i need it to show up on a certain date on a page and then again exactly 15 days later…

so say you enter the page of the site on a 1st of july, the entry that the viewer would see is that specific entry.. but then on the 2nd of july, it would be a different entry that would be showing up.. the 1st entry would only show up again exactly 15 days later, so, on the 16th of july.

i also need this to work with a regular calendar that the viewer could click on the date and view the entry that belongs to that date.

im going to try google calendar and see if i can adjust it to my site because i doubt this topic is understandable. i’m having a hard time explaining it.

anyway, the link to my site is https://guiaelasesor.com.ar/sanmiguel/farmacias-de-turnos/ in case anyone wants to see through it and help out. thanks. sorry if i posted in wrong section.
