User Query: I recently restored my iPhone from a backup, and now my Apple Calendar is a mess. I want duplicate events without losing my actual meetings. What is the safest way I should use?
Apple Calendar is great for keeping track, but sometimes things go weird.

In this blog, we’ll talk about why these duplicate events show up in the first place. Then we’ll go over a simple manual way to delete duplicate events in Apple Calendar. And if that feels too risky or time-consuming, we’ll also mention an easy way using the MailConverterTools ICS File Converter Tool
