Research: Technology for connecting to multiple calender-feeds

Hi guys,

I am planning to hook up several calender-feeds (of different locations) to my meteor-app and I am wondering what technology is available to read and process those calenders within meteor.

I am right at the beginning of my research and I guess that Google has a solution to publish a calender feed and that I can process multiple feeds within meteor?

Does anyone have some experience in this?

What tools are available?

Kind Regards
