Pretty new to calendars, because they've been a pain in the past. But it's more and more to my liking, and other apps play game a bit more too. I have older ones like friendsBirthdays and hobbyStuff And newer ones like Birthdays and Home and Hobby. How can I, on ios or on osx, merge them into 1 calendar that syncs over iCloud? I can't seem to figure this out, either it is simply not possible, or its simple and im overlooking the obvious. Secondly, is there a way perhaps to set some preferences? Each thing I add requires a 'day before reminder' or ' give me an alarm for this stuff' or any of that sorta stuff. Anyway, I hope you guys can help me get started in using calendar a bit more productive.
