Delete past events in subscribed calendar
I have subscribed to a US holiday calendar on iCal. I don't mind the past holidays showing up on my macbook iCal, however on my iPhone this is annoying. I like having my calendar app on the iPhone show today's events - future events. Not past events. With my own calendars I simply delete past events that already occured. WIth a subscribed calendar I do not have this option because I do not maintain the calendar that is being subscribed to.
Does anybody know how I can hide these events on the iPhone iCal app? I have the settings set to show/sync only events that are 2 weeks old, but they still show up!
OR
Does anyone know of a US Holiday calendar that I can subscribe to that deletes past holidays?
Further, I do not want to import a calendar that I then can maintain because I'd rather simply subscribe to one that is always maintained, etc.....the purpose of subscribing...
Thanks!
