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

Has anyone run into this problem recently? I am on an iPhone 6 on iOS 10.2.1. Now my calendar isn't showing anything before a year ago (February 4, 2016.... today being February 4, 2017). I've tried and checked all the other solutions mentioned on this thread - nothing has changed even though my calends settings are correct.

Yes. It's maddening. I have tried every solution suggested and NONE of them work. Random old and new events and appointments disappear from my iPhone, iPad and 2 Macs. Some I have entered, some are subscribed events - there's no consistency as to which disappear and which don't. Apple has no answers either. I'm going to have to buy a different calendar program to keep track of appointments and events - I don't see any other solution based on the number of others who also have not had this resolved. I find it absolutely ridiculous that Apple has not addressed this - it's a very serious problem for a large number of users.

Hey, thanks for helping with the calendar issues. I checked my settings they were already set at 6 months. However, my events especially repeated ones just disappear days after I in put them. Any help?

Are these events older than 2 weeks ago? If so, check Settings>Mail,Contacts,Calendars>scroll down to Sync in the Calendars section and set it to a longer time period.

OK, that's a mystery. You could try stopping the Calendar app, followed by resetting your phone. Double-tap the home button, locate the Calendar app (swiping if necessary), tap and hold the icon until it jiggles, tap the red minus sign. Now reset the phone by holding the on/off and home buttons simultaneoulsy 10-20 seconds until you see the Apple logo (ignoring the off slider that appears first), release and wait for the phone to restart. You won't lose any data. This may fix the Calendar but probably won't restore any missing events.

The same thing just happened to me and I'm furious! I had months ahead of planning and they all got deleted right before my eyes. FIX THIS PLEASE!

the same thing has happened to me. I entered new events on Saturday for the next few months and when I went to view them last night, EVERYTHING new I entered is gone! I'm so angry. I've been reading forums all day and have tried all suggestions and nothing is working. HELP!!!!!

same problem....i was adding another event to my calendar...after i finished putting in the event all my future events that i had entered got deleted, i am confused to how they got deleted since i did not push any delete button, only a few random events from the past and future was saved.....extremely frustrated as i had important dates and reminders set!!!!!!!!!!

This happened to me today using Week Cal. Mine had something to do with backing up with iCloud. Originally in settings I had my email account as the selected calendar to sync with. If you are backing up with icloud, try going to settings, then select to sync with iCloud Home. I also found a load of settings I didnt even realize were within the app itself since the latest update. Hopefully this works for some of you. I can relate to the frustration of losing all your important dates, which is why I like to back my data up. Good luck.

Hi, I just had the same thing happen to me. I was adding a new event to my calendar and all of a sudden the screen went entirely white. All other aspects of the phone were fine. When I returned to the calendar it was still white, so I shut off and restarted my phone and the only events that reappeared are random repeating events I had previously input. All of the other data is gone. So frustrating. Does anyone have any updated information on how to restore the lost information? Please help!

This is happened to me about 3 times, since I got my iphone last December and I don't know how to correct it or why it happens. My phone is fully charged and I go to my calendar and everything past and future in all 5 calendars is gone. This does not happen during a sync, though I have set the sync to all events just in case. It is driving me crazy and I can't figure why it is happened, but I'd love a fix.

I've called twice to ask for help with this and they say they don't know what causes it and they haven't heard of anyone else having this problem. I've also been told they look for help with issues on these forums and I should check on here. It's pretty funny that there are 50 people having issues with this and NO ONE from Apple has come onto this forum to help with a response. Thing I might switch to android.

This happens to me INCESSANTLY. I'm looking at my calendar events one second, and POOF!, the next second all of the events I've entered into the calendar- with the exception of birthdays that are on the actual contact information for a person- are GONE. My calendar settings are set to sync all events- no timeframe- and always have been. This happened to me nonstop on my old iPhone 3GS, and I was sure it was the phone causing this issue. Now, I have my new iPhone 5 in my hands and same ol' , different equipment. I have done EVERYTHING I can think of to prevent this from happening or to restore the data- including rebooting, holding home button and on/off at same time, etc.- and NOTHING works to restore the data. And then, just as magically as the data disappeared, POOF!- the data is back randomly sometime later. That "later" may be 5 mins, a day, several days. This is an absurd and EXASPERATING glitch that APPLE NEEDS TO FIX IMMEDIATELY!!! I'm starting to hate the iPhone and Apple in general when I continuously experience HUGE glitches like this that have a profound impact on what you're trying to accomplish within a feature that you DEPEND on... yet Apple has "never heard of that problem before". You suck, Apple. Don't send your problems out into the real world, to users who just gave you $800 for another glitchy piece of equipment that never solves your software issues.
