Calendar duplicated all day events on sync

While syncing iPhone, my desktop calendar duplicated all repeated day events in both the future and the past. Now I show over 30 events on every day in every year. How can I reset to get only the accurate calendar events back to my calendar without losing the original information?

iMac 27″, macOS 10.15

Thank you so much for the reply! The calendar I use on my desktop is not linked to iCloud or an email server. I never had an issue until my last sync with my iPhone after updating to Ventura, and I normally sync using calendar replacement for my phone calendar. Here is what my calendar looks like since the sync. Older dates have even more all day repeated events.

Any suggestions to eliminate these repeats without having to manually update every entry would be appreciated!

Please check which is your Default email Account for the Calendar on your device? Settings > Calendar > Default Calendar



All the devices sync with an email client server which hosts your calendar. If you have a Calendar on iCloud that will not sync with Google Calendar. Settings > Calendar > Default Calendar [Choose what you want]. What you add (Event) on iPhone Calendar is synced with default calendar unless you have chosen a specific calendar at the time of event creation.



To which email account are the calendar events synced with your iPhone? This is not clear in your post
