Why do my calendar events get deleted from my iphone while I'm viewing the calendar?

This worked for me, thank you very much! Left now wondering, why, why did this happen?? I rely on my calendar and when back to check on when something occurred and it was GONE. Now restored....

If you have made a backup for your data before and it contains your lost calendar, then you could certainly restore deleted calendar from iPhone

1. Connect your iPhone with iTunes on computer

2. Right-click or control-click on the iPhone icon under iDevice on iTunes

3. Select "Restore from Backup" from the given options

4. After it finishes, your data are back to your iPhone

This is an updated fix for iPhone 5s on 8.1.1., and assuming you have an iCloud backup of your data. Open Calendar on your iPhone. Click on "Calendars" at the bottom. Click on "All iCloud" to put a check mark next to it. Click "Done" at top right. Your calendar will now be restored from iCloud.

I had this exact thing happening also to me (IOS 7.1.2) with an Exchange account. this morning i was going to jump into my car to join an online conference, opened the calendar app and before my eyes, saw the event disappear. This also happened with subsequent events during the day, and after trying more or less all the first mentioned "tricks", the only way I was able to get the events back was to go into Settings > Mail, Contacts, Calendars > Exchange and turn Calendars off (Delete from my iPhone), then switch it back on and wait for some minutes. Voilá, the events reappeared.

I'm all fine by doing this, but it would be nice of Apple to tell me WHY this is happening.

This worked perfectly! Thank you!!

randers4, thank you very much for your simple and easy fix.

I recently found I was missing all my past events, except for auto-populated birthdays from my Facebook, and it was quite upsetting.

I followed your simple instructions, under "Settings", "Calendars", "Sync", selected "All Events" rather than a set length of time, and VOILA!! All my past events magically re-appeared.

Having said all that, I'm still keeping a pocket calendar in my purse. :-) I don't trust technology.

Thanks again for your suggestion.

Hi all, I've been on to apple support for a while, but not sure if anyone on here knows how to get me out of trouble. I had a situation where events that were entered into my iPhone didn't 'synch' to my outlook account online and hence weren't showing in my outlook on PC. So I had a load of appointments that were solely 'saved' on my iPhone. I realised this morning that this had been going on for a few weeks (I'd been using my phone to update diary exclusively while not in my office). This is obviously the opposite type of problem, in that the appointments were on the phone but not on a web based account etc. All the appointments disappeared as they were 'Hidden' and then 'unhidden' in the calendar app (during a chat with apple support to try and get them moving across to outlook again). So now I don't have any appointments either on phone or in outlook etc. It is driving me insane. Anyone got any ideas?

I have a variation of this problem that is driving me crazy! I routinely sync events from my iPhone 5, OS 9.01, to Yahoo Calendar (I know, I should leave for Gmail, but I've been on Yahoo forever). Because I use my iPhone calendar as a "diary," I have always set the sync function to "All Events"; and up until a couple of years ago, maybe a little less, that worked: I could look all the way back to the 90's and see events, both in Yahoo and on the phone. But about that time, the iPhone stopped syncing all the way back: It will only sync for six months back, to Yahoo. If I create an event on my phone for Yahoo that's older than that, right now, it will appear briefly on the phone, then disappear--but I can see it on the Yahoo Calendar on my PC.

An hour ago, searching Yahoo Help, under Sync Yahoo Calendar and Yahoo Contacts with iOS devices I came across this information, and I wonder: does this account for it? Here it is: It's only possible to sync Yahoo Calendar events from the last 6 months, and those up to one year in the future. Events outside of these time frames won't be synced to your device.

So, does this mean that the problem is not with the phone, but with Yahoo? If anyone knows, save my sanity--please!

Unfortunately, I think you're right, and I just found this out as well, after quite a bout of frustration. I just got my "scheduled holidays" from my employer & as I normally do-in put them all in my iPhone calendar.. Well, as soon as I got past todays date, but next year, the events would disappear after I input them! It was driving me crazy trying to figure out what was going on. I then discovered the events, plus all my test events, were indeed in the calendar when I logged in via the web app. They just weren't syncing with my iPhone. So after doing some digging, I also found the statement you noted. This MUST be a new thing. Reason I say that is that there are other events on my calendar that I had put in some time ago, but they are still there, even though they are more than a year in the future. So they must have made this change recently, but grandfathered any existing events.

So-I would encourage you to voice your displeasure with this to Yahoo. I did via the "was this helpful" feedback section of the page where the sync statement is. I outlined it via the "other" tab. This is a real pain, especially for folks that plan well ahead for vacations, etc.

This helped me thanks heaps!

Same problem here. I'll make a date range for an event. Then the very next day I go into my calendar and the dates are magically not there. I reverted to using a paper calendar on my wall because I can't stand this iBullcrap. never used to happen on my iPhone 1-4.

Thank you for the information. This worked !!

Ta-dah! This finally worked! Thank you!

Google / Gmail calendar had this problemf or me, it wasn't to do witht eh "All events" sync setting.

Turning off Calendars on the Google account, then quitting the Calendar app and re-enabling the calendar seemed to magically bring back the old events.

Seems to be a Gmail only issue, didn't do it with iCloud.
