Bug by iPad about crashed with calendar

It is caused by a bug caused by daylight saving time adjustment on March 31 to Apri 1.

As a fix, remove all occurrences of the day you have to April 1,  2013. You can add them to a time that is in the middle of the day to replace them.

Once there is no all day events on 04/01/2013 March opened in all views.
