How to Combine Multiple Google Calendars Into One Shareable Link

5 min read · Works with Apple Calendar, Google Calendar, and Outlook

Google Calendar makes it easy to see multiple calendars at once — but that merged view lives inside your Google account. There's no built-in way to export a combined feed that others can subscribe to, or that works in Apple Calendar or Outlook. Calendar Combine solves that.

Why Google Calendar can't do this on its own

Each Google Calendar has its own private ICS URL, but Google doesn't offer a way to merge several into a single subscription link. If you share one Google Calendar, the recipient sees only that calendar — not your combined view. And if they use Apple Calendar or Outlook, they need an ICS/webcal URL, not a Google Calendar share link.

Step 1 — Get the ICS URL for each Google Calendar

For each calendar you want to combine:

1. Open Google Calendar on the web
2. Click the three-dot menu (…) next to the calendar name in the sidebar
3. Select Settings and sharing
4. Scroll down to Integrate calendar
5. Copy the Secret address in iCal format (ends in .ics) for private calendars, or the Public address in iCal format for public ones

Repeat for each Google Calendar you want to include.

Step 2 — Create a free Calendar Combine account

Go to calendarcombine.com and sign in with Google or your email. The free plan supports up to 3 Google Calendar ICS feeds at no charge.

Step 3 — Paste in your ICS URLs

Create a new combined calendar, give it a name, and paste in each Google Calendar ICS URL one at a time. Calendar Combine validates each feed and pulls in the calendar name automatically.

Step 4 — Copy your merged subscription link

Once your calendars are added, Calendar Combine generates a single stable feed URL. Copy the webcal:// version for Apple Calendar and Outlook, or the https:// version for Google Calendar.

Step 5 — Subscribe and share

Subscribe to the merged feed in your calendar app, then share the same link with anyone who needs it. They subscribe directly in their own app — no Google account or Calendar Combine account required.

Common uses

• Co-parents — share a combined school + activity calendar between people who use different calendar apps
• Remote teams — merge a shared Google team calendar with individual calendars into one feed for non-Google users
• Families — combine personal, kids’ school, and shared household Google Calendars into a single subscription link
• Subscribe to multiple Google Calendars in Apple Calendar — Apple Calendar can subscribe to individual Google Calendars, but Calendar Combine lets you merge them first so you get one clean feed

Why not just share a Google Calendar directly?

Google Calendar’s share feature lets others view your calendar inside their own Google account — but only there. It doesn’t produce a merged feed URL, it doesn’t work across apps, and recipients must be signed in to Google. Calendar Combine gives you a single webcal:// or https:// link that works everywhere.
