Getting old calendar events back

There are two things you can do about this, one on the device and one on iCloud.com:

• On the device, you can setup to sync the calendar only for the events in the past two weeks (that's the shortest duration in the past you can set it to).

  1. Do this by going to Settings → Mail, Contacts, Calendars
  2. Under the Calendars section, go to the Sync submenu
  3. Select Events 2 Weeks Back

• Login to iCloud.com, go to Calendar and follow Apple's help on "Delete or hide events":

  To automatically hide past events, choose Preferences from the Action pop-up menu , click Advanced, select “Hide events n-days after they’ve passed,” then enter a number of days.

  Set it to 1 day (that's the minimum allowed).

Go to Settings and click iCloud and turn on Calendars.

If that doesn't work, while in your Calendar, look at the bottom - "Today," "Calendar," and "Inbox." Click on Calendars. Somehow my "Home" calendar (which is where I save most entries, as opposed to "Calendar" or "Work") was unchecked. I couldn't see any old or future entries, and when I added entries and hit save, the day would be empty. When I re-checked "Home," everything reappeared.

It just wasn't showing "Home" entries. I hope your problem is this simple because I know how you feel like you're losing your mind when something like that happens!
