How to Merge Google Calendars into One? Best Ways

Managing multiple Google Calendars can quickly become overwhelming. Many users maintain separate calendars for work, personal life, shared projects, or different Google accounts.


Viewing events across calendars may be convenient, but when you want a single, unified calendar, things can get tricky. That’s where learning how to merge Google calendars into one becomes essential.


In this guide, we’ll explain all possible methods to combine Google Calendars, including manual techniques and a professional automated solution using the SysTools ICS Merger Tool. Each method is explained with clear steps, benefits, and limitations so you can choose what works best for you.


Why Do You Need to Merge Google Calendars into One?


Before diving into the methods, let’s understand why users prefer to merge Google calendars into one:


  1. To avoid switching between multiple calendars
  2. To manage events from different Google accounts in one place
  3. To create a single calendar for backup or migration
  4. To share a consolidated calendar with colleagues or family
  5. To improve scheduling accuracy and reduce conflicts

While Google allows you to view multiple calendars together, it does not offer a direct “merge” button. Therefore, you need alternative approaches.


Method 1: Use the Google Calendar Move to Calendar Option


This is the most straightforward way to merge calendars when both calendars are accessible from the same Google account.


Steps to Merge Google Calendars into One Manually


  1. Open Google Calendar in your browser.
  2. In the left panel, expand My Calendars.
  3. Select the calendar containing events you want to move.
  4. Click on any event and choose Edit.
  5. In the calendar drop-down, select the destination calendar.
  6. Save the changes.
  7. Repeat for all events.

Limitations:


  1. Extremely time-consuming for large calendars
  2. No bulk selection option
  3. Risk of missing events
  4. Not practical if you need to merge Google calendars into one frequently.

Method 2: Export and Import Google Calendars Using ICS Files


Google Calendar allows exporting calendars in ICS format, which can then be imported into another calendar. Steps to Merge Google Calendars into One Using Export/Import


  1. Open Google Calendar Settings.
  2. Go to Import & Export.
  3. Click Export to download the calendar as a ZIP file.
  4. Extract the ZIP file to get the .ics calendar file.
  5. Switch to the destination Google account/calendar.
  6. Go back to Import & Export.
  7. Upload the ICS file and choose the target calendar.
  8. Click Import.

This method effectively helps merge Google calendars into one by transferring events in bulk.


Drawbacks of the Export/Import Method


  1. Duplicate events may occur
  2. No advanced filtering or preview
  3. Limited control over merging conflicts
  4. Repeating events can behave inconsistently

Method 3: Share One Calendar and Copy Events


Another way to merge Google calendars into one is by sharing one calendar with another account and copying events. Steps Involved are:


  1. Open Google Calendar settings.
  2. Select the calendar you want to merge.
  3. Share it with another Google account with the Make changes permission.
  4. Log in to the destination account.
  5. Open shared calendar events.
  6. Copy events manually to the primary calendar.

Why This Is Not Ideal


  1. Entirely manual
  2. Not scalable
  3. High chance of errors
  4. No automation
