Loss of Calendar

I've just updated my iphone to IOS27 and now all my calendar events have disappeared. I do not sync to iCloud and I have not done a manual backup of my phone for some time. All of the calendar events are manual inputs. How do I recover all of these please? Thanks in advance.

I'm afraid, if you did not back up your iPhone before you started the upgrade to iOS 27, as recommended in the related article, your calendar data is gone.


Or did you use a 3rd party calendar app?
