How to Remove Duplicate Entries in an iPhone Calendar

If you use your iPhone's Calendar app to keep track of your daily schedule, duplicate calendar entries can make your day look twice as busy as it really is. In many cases, you can simply delete the duplicate entries on your iPhone. This is the fastest solution if you have accidently accepted an invitation on your computer and again on your iPhone. In some cases, duplicates can be caused by two different calendars syncing to the iPhone, creating dozens if not hundreds of extra entries. If this is the case, you can hide or delete the specific calendar within the app that is causing the problems.

Deleting Duplicates Entries From the iPhone

Launch the "Calendar" app on the iPhone. If there are only a couple of duplicate entries, you can delete them quickly.

Locate a duplicate entry and tap it with your finger.

Tap the red "Delete" button to remove the duplicate.

Hiding and Deleting Duplicate Calendars

Examine the iPhone's Calendar entries to determine if specific calendars are causing duplicates. For example, if you have and "Outlook 1" and "Outlook 2" calendar, these may be the same calendar imported twice.

Tap the "Calendars" button in the upper left corner of the screen.

Tap the duplicate calendar to remove its checkmark. This hides that calendar's entries. Tap the "Done" button.

Examine your calendar events again to ensure you are not missing any important events while the duplicate calendar is hidden.

Delete the duplicate calendar if desired by navigating back to the Calendars screen and tapping the blue "Arrow" on the right. Scroll down the screen and tap the red "Delete Calendar" button. The calendar is removed from the app.
