If you mainly want to see all your schedules in one place, share each account's calendar with the account you use most: Google Calendar then shows them together in one view. To work inside each account, use Google's account switcher or separate Chrome profiles. WebCatalog Desktop fits when you want each account's Google Calendar open in its own window, signed in at the same time and grouped with that account's Gmail and Drive.
Combine calendars by sharing them between accounts
A calendar belongs to one Google account, but you can share it with another account. This is often the simplest answer, because you get one combined view without switching at all.
In the account that owns the calendar, using Google Calendar on a computer:
- Under My calendars, point to the calendar, select More (three dots), then Settings and sharing.
- Under Shared with, select Add people and groups.
- Enter the email address of your other Google account.
- Choose a permission level, such as See event details or Make changes and see event details, then select Send.
- In the other account, open the invitation email and select the link to add the calendar.
The shared calendar then appears in the second account's calendar list, with its own color. You can also start from the receiving side: next to Other calendars, select Add, then Subscribe to calendar, and enter the other address to request access.
Work and school accounts may not allow this. Your administrator decides whether you can share a work or school calendar, so check before planning around it.
Switch accounts in Google Calendar
To open each account's calendar directly, use Google's account switcher: select your profile picture in the top-right corner, choose Add account, and sign in. Afterwards, the same menu switches between accounts.
This is fine for occasional checks. Since every account uses the same Calendar page, look at the account menu before creating an event, so the invitation doesn't go out from the wrong address. Your default account is usually the one you signed in with first, and Google may use it when it can't tell which account you mean.
For more separation, Chrome profiles give each account its own browser window with its own bookmarks and history.
Manage multiple Google Calendar accounts with WebCatalog Desktop
Google doesn't offer a Google Calendar desktop app for Mac or Windows. WebCatalog Desktop turns the web version into a desktop app that opens in its own window with a Dock or taskbar icon, and its profiles keep each Google account signed in separately.
- Download WebCatalog Desktop and add Google Calendar.
- Open WebCatalog Desktop and go to Profiles.
- Select Add profile, then name and customize it, for example "Work."
- Open Google Calendar with that profile and sign in to your work Google account.
- Repeat for other accounts, such as "Personal" and "Client A."
You can then keep your work and personal calendars open in separate windows at the same time. A profile can be reused across apps, so the Work profile also signs in to Gmail and Google Drive with the same account. The profile help article covers the details.
To keep things together, add each account's apps to a space, such as a Client A space with that client's Calendar, Gmail, and Drive. Spaces group apps; profiles are what keep the logins apart.
WebCatalog Desktop doesn't merge calendars from different accounts. For a single combined view, use calendar sharing as described above.
Frequently asked questions
Can I see free/busy times without sharing event details?
Yes. When sharing, choose See only free/busy (hide details). The other account sees when you're busy but not event titles or locations, which suits sharing a work calendar into a personal account.
Why don't I see the shared calendar in my other account?
The recipient has to open the invitation email and select the link to add it. If you requested access with Subscribe to calendar, the owner must approve the request first.
Conclusion
Share calendars between accounts for one combined view, and switch accounts when you need to work inside each one. If you want every account open and signed in at once, download WebCatalog Desktop.
