Set Calendar dates in iFrame

Hi All,

this is not strictly speaking a Ghost question, but I hope it would still be possible to get help. I am embedding a Google Calendar here. I have done so by writing an html field with

<iframe src="https://calendar.google.com/calendar/embed?height=600&wkst=1&ctz=Europe%2FAmsterdam&bgcolor=%23ffffff&src=ZmM4OTRjMDAwZmUwZTRhZGE3ZTgzZjQyYTkwNWE3ZDFiNjYzNTViNDhjZWFkYzJiZTY4YThkMGZmYTRjODIwZEBncm91cC5jYWxlbmRhci5nb29nbGUuY29t&color=%239e42b4" style="border:solid 1px #777" width="800" height="600" frameborder="0" scrolling="no"></iframe>.

I am looking into easy ways to display only selected dates of that calendar, between the 11th and the 14th of June, which are the dates where a conference will take place. I was able to make some other modifications (title, border, etc.) but I do not know how to handle the dates, because Google does not have an immediate way to do that in their customisation.

Also, searching on google I could not understand how to do that (or if this is at all possible).

Do you know if this is possible?

Best
