"I use the calendar on my IPad mini a lot, but when I went to look at an event from 6 weeks ago, I realized all my events except the recurring events from more than 30 days ago were missing. I found online that I should change my "sync" under settings->calendars to something more than 'the last month', which I did. I changed it first to 'all events', waited about 30 minutes, and when my past events still didn't show up I tried again with '6 months'. Still none of my past events are showing. I don't use calendars on any other devices (Mac or phone). Any other suggestions on how to restore my events?" - from adina_35mm on Apple Support Communities.
