I have a holidays calendar that is time-limited (lasts only till end of 2017) and also read-only. I have only a handful of holiday, calendar, and birthday apps and widgets and I've checked several times into them but I can't figure out where this holiday calendar is coming from as I can't see its details from the calendar itself, either. I also can't remember where I got it from. Since I was able to make copies _and_ add reminders to my new holidays file, I can now delete the limited, read-only one as what I created is so much better. Does anyone have any tips on trying to determine where this calendar came from? I'd greatly appreciate any help in this regard to do this. Thanks!
