What is this symbol mean???

[fightcrazy]

I have the 5S, Just added the US Holiday Calendar and next to the Calendar there is this small circle with an i in the center. What does this symbol mean? When I see things on my phone that I don't understand (fairly new at iphone) I think right away I caused an error. Long time Android hacker who feels not yet at home with the iphone 5S but getting better.
Thanks for putting up with my dumb *** questions,

That's the "Info" 'button' - you can tap it and up will come a popup with details you can modify about the item... in this case, the feed for the subscribed calendar.

Was hoping that's what it was, gave me the choice to use different colors for the new US Holiday Calendar. That it was an error because it was red. Lost the rest of my hair from worrying. I'll never learn.
Thanks again for the help, great forum,
Vinny
