How Many Calendars does ICS allow?

There’s not really any functional limit, but there are some practical limitations.

Are you planning to put all of these calendars into a single shared shortcode? I would not recommend that unless each one only has a few events per month —?the display will blow out beyond usability if there are a lot of events.

The other matter is performance… the parser has to load all of those calendars and put their data into a single PHP array for output on the page. Your server may run up against memory and processing timeout limits with that much data.

If you’re planning to put these into separate calendar shortcodes (i.e. on different pages), then it shouldn’t be a problem at all. A site could have thousands of pages with a different calendar on each one and it should be just fine.

Hi.

I tried to use two calenders. But I can see only the items of one calendar. What is wrong here?

[ics_calendar url=”https://calendar.google.com/calendar/ical/xxxxx/basic.ics” title=”true” color=”#008000 #ffa500″ #800080 solidcolors=”true” “https://calendar.google.com/calendar/ical/xxxxxup.calendar.google.com/public/basic.ics” title=”true” color=”#008000 #ffa500″ #800080 solidcolors=”true”]

I’ve also tried several other options. I also manage to have both calendars displayed one after the other. But I want the dates of both calendars to be displayed together in one calendar.
I don’t have a pro version yet. Is that maybe because of that?

Each attribute can only occur in the shortcode once. For multiple feeds, you need to put all of the URLs into the one url="" with the URLs separated by spaces or the pipe character, as indicated in the docs here, under “Multiple Feeds in One Calendar”:
