Feed an EXTERNAL RSS into a wordpress calendar

Hello!

As the title states I’m having some trouble getting an external RSS feed to show up as events in a wordpress calendar widget/plugin. The RSS is created with a system called Basetool v2, and the goal is to make the events in the rss appear as events in a calendar.

I’ve tried to find a calendar plugin/widget with a feature which makes it possible to import a rss but with no success… Also have been searching for solutions to this problem, but only find questions about how to generate an RSS from events created within wordpress and it’s calendar.

Responses and suggestions would be greatly appreciated.
Thanks
