I have tried everything these kind folks have discussed. To list them, I have: held down home and lock bottons to restart/reset iphone 4. I have added test events on the same days I have missing events to see if the missing events "pop up randomly". I have changed the sync timeframe in the calender settings to "all events". Nothing has made my missing events show up.
I am missing all the events for the past two weeks (first two weeks of august) and future events (unknown to what extent) as well. Whats wierd is that an event I made yesterday is there, but the rest of the week is gone. I need a calender because this is how I keep track of my work hours for my small business. Right now Im thinking of downloanding a seperate Calender app and leaving iphones app behind, for good.
Any additional help would be great, and APPLE, Feel free to chime in, its your application that is failing me at the moment. I have been a Mac and iphone user since, well, since the beginning.
P.S.
I noticed this after I changed the email address for my iCloud account. I dont know if that is the cause, because in theory I have events that I added with the old address that still appear in my calender.
