Is there anyway to see old entries on the iPhone calendar app

The built-in calendar app only goes back one year, but there are many 3rd party calendar apps in the app store that can cover any range. The Week Calendar app I use can show me back to 1997, when I first started using it on a Palm Pilot. The calendar database is pretty much unlimited; the only restriction is the app itself.

It will go back about 13 months

To see older ones sign into icloud.com in Safari

Sure, for stuff within last year you can use build search in Calendar app. For older events go manually (scroll to it) to date when it happened.

That’s not much help. The whole purpose of the question is not to have to manually look for something that may be embedded in between a hundred entries

Reading the other posts in the thread might help.
