Hey @Simoncarr,
Thanks for reaching out.
The main hindrance to having the calendar load on the home page thus far has been neither a concern of performance nor of SEO/redirect/etc. issues. It has really mainly just been a technical limitation of our plugins based on how they work.
In the next version of The Events Calendar, version 4.3, there will be full support for embedding complete calendar views anywhere you want—even on the homepage. And that would be fine—no permalinks issues, etc.
Until that release happens (which should be some time in the next two to four weeks, if all goes to plan), then the only way to approximate the functionality of a homepage calendar is to use the methods in this knowledgebase article → https://theeventscalendar.com/knowledgebase/how-to-make-your-calendar-your-sites-home-page/
I hope this information helps!
Cheers,
George
