How to Merge Google Calendars

Published on

When it comes to calendar providers, Google Calendar is considered amongst the best in the industry, used by individuals, students, small businesses, and large enterprises. As years go by, Google Calendar has been improving, adding features such as Google Appointment Schedule, API access for third-party tools to build on top of it, and much more.

Given the benefits Google Calendar offers, individuals use it for scheduling their personal life and professional lives and managing multiple calendars. While the benefits of Google Calendar are undeniable, managing multiple Google Calendars is time-consuming, as you have to switch between accounts to join meetings, schedule meetings, or see and plan your schedule.

The first solution to this problem that comes to mind is, how do I merge Google Calendars? To answer this question, we’ll thoroughly explain how to merge Google Calendars, the benefits of each method, and the drawbacks.

How to Merge Google Calendars by Exporting and Importing?

The first method of merging two Google Calendars is by sharing the first Google Calendar and importing it to the second Google Calendar. As an example, let’s call the Google Calendar we’ll share Calendar A, and the Google Calendar we’ll import, Calendar B.

To merge two Google Calendars, Calendar A, and Calendar B, we should follow these steps:

  1. Open Google Calendar
  2. Hover the mouse cursor over the calendar you want to export (Calendar A).
  3. Click the three-dot menu icon.
  4. Click Settings and Sharing on the menu.
  5. Locate the Access permissions for events option, and check it. Google Calendar warns you that: Making your calendar public will make all events visible to the world, including via Google search. Click Ok. On the same option, select See only Free/Busy time.
  6. Scroll down and copy the Public Address in iCal Format.
  7. Open Google Calendar B.
  8. On the sidebar, near the bottom of the page, click Other Calendars +.
  9. Click From URL in the drop-down menu.
  10. Paste the link you copied earlier (step 5) and click Add Calendar.
  11. Your new calendar will appear in the list under Other Calendars + once it’s merged. You can then rename it and change its color settings

This method clones events from Google Calendar A to Google Calendar B. If you want to do a two-way merge, please repeat the same steps to send calendar events from Calendar B to Calendar A.

💡 Pro Tip: If you want to automatically merge multiple Google Calendars in less than one minute, consider using OneCal. The first method is done by manual sharing, requires lots of steps to merge more than 2 calendars, and it’s it requires you to make your Google Calendar public.

Cons of Merging Google Calendars by Exporting and Importing

  1. Little Exporting Privacy when merging Google Calendars: When exporting the first calendar (Calendar A), Google Calendar warns you: Making your calendar public will make all events visible to the world, including via Google search. This means that your private Google Calendar events will be available to the public. This is a major concern if you’re trying to export a work Google Calendar, as meetings might be sensitive (same for your personal Google Calendar). The only way to protect yourself is by selecting See Only Free/Busy.
  2. Google Calendar users (team members) can’t see your busy slots. In our example, we shared Calendar A to Calendar B. In that case, team members of Calendar B won’t be able to see that you are busy at the time slots of Calendar A, even though you have merged both Google Calendars. This happens because when they use the Find a Time feature on Google Calendar, Google Calendar only checks for busy slots on the primary calendar, not on the imported calendar. This leads to meeting conflicts and confusion.
  3. Hard to set up. Merging Google Calendars takes a couple of minutes, as you’ll have to follow 11 steps for each Google Calendar to merge. Furthermore, you might have to troubleshoot possible issues.
