The calendar on my ipad turns off as soon as I reach march 2013. February and april are OK though. I can´t add any events in march 2013. Why? Anyone else? When I add events in march 2013 in outlook or on my Iphone, there are no problems.
It's a bug that must not have been fixed in iOS 6 from 5. Change your April 1st event from an all day event to a specific time. Has something to do with the time change that day which causes problems with the iPad. Something like that I heard here.
