Why do I have a calendar called weather? And has nothing to do with anything I have a calendar called "Weather: Auckland, NZ" 
The Weather calendar on the sidebar is checked and it's called "Weather: Springfield, MO" And the "calendar" shows three days for my zip code. Of course I can share, add, use, save, import, export, make into orgami, but can't delete. WHy does it exist? Where did it come from? I haven't been to any of the places associated with the calendar. I live in the zip code. OH, and it's it's own calendar. Not associated with any other emails or calendars. A color all it's own. Which, of course, I can also change. Any idea?
It is a app from MetService (MetService NZ Weather) on App Store, that you must have downloaded.
