overlayed public calendars in HTML

[beholdtheloaf]

I have a public calendar "calA" that I (or anyone) can display in HTML format via the URL https://servername/mylogin/calA.html. Works fine... Now I'd like to display in HTML both "calA" and a new public calendar "calB", overlayed in the same display. Is there a way to do that?

Welcome to the forums,

These are all zimbra calendars correct? Right click the word calendars then 'link to shared calendar':

Thanks for the reply, Mike. Yes, both calA and calB are Zimbra calendars that I have created - sorry I neglected to mention that. These calendars record upcoming events of interest to a wide audience. I like the fact that non-Zimbra users can view calA publicly as calA.html. What I'm looking for is something that everyone can view in HTML form that has both calA and calB together.

Is there some special syntax I can use that signifies something like "calA-plus-calB.html"? Or can I create a Zimbra calendar named "calA-plus-calB" that links to both calA and calB? It seems that if I "link to shared calendar", as you suggested, the new link is just to a single calendar.

Hm... Have I stumped the Zimbrans? Or have I phrased my question badly? To restate the problem: I have two Zimbra calendars, and I'd like to share them so that the union of the two calendars can be viewed as a single HTML document (without viewers having to subscribe to the calendars).

I have a user asking for the same too.

There are several zimbra calendars, and they are wanting to be able to see all of them on one page to quickly see which calendar has free time.

If you access both shared calendars in Outlook, I believe you can overlay them.

Here's a page that describes how to do it: Overlay Calendars in Outlook 2007 (like Google Calendar does) :: the How-To Geek Of course you do have to have Outlook and Zimbra Connector for Outlook.

ewilen,

Thanks, we may be able to use that in our situation.

I have ran into a similar problem.... one thing to try would be to export each calendar and then import them into a single shared calendar which would then be shared to the public. you would have to schedule these commands in cron.

Yes, if it's any help, note that the public html calendar views contain links to .ics versions at the lower left. So,

(a) If people have iCal, they can subscribe to both and then show them on a single calendar.

(b) You can do as bryan suggests.

(c) You might see if icalshare.com, ifreebusy.com, or fusecal.com could be lassoed into concatenating the data for you.
