iPhone calendar keeping skipping back to same date

Same issue for me as well on iOS 14.7.1. I would add this has been an issue for me since iOS 13.0. I restart my phone once a week. I have removed all linked calendars, then relinked them. iOS Calendar app always goes back to September 2019. Something really important must be going on there that all of us on this thread need to know about?

This issue has happened for the last few years. My native calendar app reverts back to Oct 4 2019 which is the day I activated this iPhone 11 Pro. I have to click “today” in order to see relevant appointments, etc.

Hey… nope… mine’s a 4 year old model… jumps back to Oct 22, 2019 (670 data’s ago… today). It does this each time I restart the calendar. Very consistent. Has anyone from Apple responded on here with an actual troubleshooting tag or an answer?

This has happened to me on two phones now, jumps me back to March 13th 2020 which happens to be the day our area shut down for the pandemic so it’s a little upsetting. I had an iPhone X and just in the last month got an iPhone 12 mini and it’s still happening on this phone…. Really wish there was a fix cause it’s super annoying and I don’t want to be reminded of that date anymore!

I thought I read a couple weeks ago on this thread that the next iOS version fixes this. Is that not the case? I realize the response was not directly from Apple.

(My last post was deleted by Apple because I referred to testing I didn’t realize that went against guidelines, apologies.)

I have exactly the same issue.. mine skips back to27Sep2019 on my iPhone 12 Pro Max.. not sure why.. I have had iPhones for many years.. would love to fix it.. it does not happen on my MacBook Air or iMac

This has been happening to me as well (with an iPhone 7s purchased in 2018 or so. It goes back to September 2019 EVERY TIME I open my calendar now, multiple times. It’s validating to learn I’m not alone but how can we get this fixed. Also, why is it happening more and more? Like it used to be once a day and now it’s always.

I’m assuming, having trawled the replies, that apple has given up responding. I’ve found that a hammer stops this from happening again. But it’s a bit of an issue as that seems to disable all the other functions as well.

I am a newer first time smartphone user and the apple iphone was recommended as an easier transition to a smartphone, but honestly, apple has some much needed fixes. First and foremost is the issue with the calendar flipping back to 2020! I got this phone in May 2021 and the calendar was fine until the first update. Thats when it started flipping back and hasnt been corrected since. I have entered calendar reminders on the wrong dates because of it. Seriously apple….Why has there not been an update to fix this yet???

Supposedly iOS15 takes care of this issue, but I saw someone post earlier that they still have the issue after updating. It’s pretty frustrating. It appears Apple has been unable to figure this one out.

I posted a similar solution and it turned out to be a temporary fix, about a week or so. It's now flipping to a "new" old month (March 2020) after I deleted all entries for the prior problem month of Feb. 2020.

I’m using 15 and it’s still skipping back to last year. It just did it again now.

it’s so annoying because I see appointments that I didn’t know I had and then I realize oh I’m in last year after my heart skips a beat.

My Calendar App does this as well. Keeps going to Sept 2019 !! Annoying !!! Currently Im using iPhone 12 Pro Max

I restart it regularly. This shouldn’t happen. It’s been going on thru various updates and phones

Well, I was going to comment yesterday that I upgraded to iOS 15.1 and it solved my issue. It worked well yesterday, but not today. For some reason now, it only goes one year back to November 11, 2020. Pretty random & still frustrating. I would have thought that Apple would have figured this out by now.

I wish Apple could figure this one out. Twice this month, I have screwed up a calendar, appointment because it’s going back to November 2020. I wouldn’t have thought this would be that difficult to troubleshoot and come up with a solution.
