How to Remove Duplicate Google Calendar Events?
Repeated entries accumulated in your Google Calendar are a common problem among users. When you have multiple calendars with thousands of events. Finding and removing duplicate events is a big task. To help you, I have several ways to easily delete duplicate events in Google Calendar.
Google Calendar is a popular choice for managing schedules, meetings, reminders, and events. Many professionals and personal users use it to schedule their events. But if you don’t pay proper attention. Then, the duplicate events problem will arise.
Why are Similar Events Appearing in Google Calendar?
Duplicate events in Google Calendar do not create themselves. The reasons for having similar duplicate calendar entries are synchronization issues, repeatedly creating events, etc. There are other reasons for this that I have mentioned below.
- When a user syncs the same calendar from multiple devices, such as smartphones, computers, and laptops. Sometimes synchronization failure creates the duplication, or running the same calendar again and again from different devices may cause the duplication issue.
- You are importing the same caelednar files in Google more than once. This is because Google Calendar cannot detect duplicates, but creates another copy of the same event. This is why there is an issue with Google Calendar duplicate entries.
- Many third-party apps like CRM tools, project management apps, etc., that are integrated with Google Calendar, can create multiple entries of the same meeting due to sync errors or incorrect settings.
- If you have moved your calendar from one platform to Google. Some events already exist in your Google Calendar. After the migration, you now have similar events.
- Many users are subscribed to the shared calendar. If you have subscribed to the calendar multiple times, Google will display the same event repeatedly.
These are the common reasons why duplicate events are seen in Google Calendar. Now, let’s see the reasons to remove duplicate Google Calendar events.
