rss reader to read the pub date but that is the date of the event
I want abr this an RSS reader reads the publication date of the event that is at all possible without getting problems with Ical?

sorry i didn’t understand your question, could you rephrase?

Have a look at the link times

and they visit at the event 9.Lauf Free Style Trial Series
The date above is the date on which the event is but it should be the date when it was published on my site.
