How to Add Apple Calendar to Google Calendar (And Keep Both in Sync)

If you use Apple devices at home and Google Workspace at work — or you're just trying to stop missing events because they live in two separate apps — getting Apple Calendar and Google Calendar to talk to each other is a genuinely useful thing to know how to do. The good news: it's possible. The less tidy news: there are a few different ways to approach it, and which one makes sense depends on your setup.

What You're Actually Trying to Do

Before diving into steps, it helps to separate two different goals that often get lumped together:

1. Seeing your iCloud Calendar events inside Google Calendar
2. Seeing your Google Calendar events inside Apple Calendar

These are not the same operation, and they don't use the same method. Most people want both, but the direction matters when you're troubleshooting or deciding on an approach.

Method 1: Add Google Calendar to Apple Calendar (The Easier Direction) 📅

This is the more straightforward path. Apple Calendar natively supports Google Calendar as an account type.

On iPhone or iPad:

• Go to Settings → Calendar → Accounts → Add Account
• Select Google
• Sign in with your Google account credentials
• Make sure Calendars is toggled on

Once connected, your Google Calendar events will appear directly inside Apple Calendar, color-coded and synced in real time over the internet.

On Mac:

• Open System Settings (or System Preferences on older macOS) → Internet Accounts
• Add your Google account and enable Calendar access

This gives you a live, two-way sync — changes made in Google Calendar show up in Apple Calendar and vice versa.

Method 2: Share iCloud Calendar with Google Calendar (The Trickier Direction)

Getting iCloud Calendar events into Google Calendar requires a few more steps, because Google Calendar doesn't have a native "add iCloud account" option the way Apple Calendar does with Google.

The workaround relies on iCloud's public calendar sharing feature, which generates a link in the iCal format (.ics). Google Calendar can then subscribe to that link.

Step 1 — Share your iCloud Calendar:

• On a Mac, open Calendar, right-click the calendar you want to share
• Select Share Calendar → Public Calendar
• Copy the link provided (it starts with webcal://)

On iPhone/iPad:

• Open Calendar → tap Calendars at the bottom
• Tap the ⓘ next to the calendar name → Share Link

Step 2 — Convert the link for Google:

• Change webcal:// at the start of the URL to https://

Step 3 — Add it to Google Calendar:

• Open Google Calendar in a browser (this doesn't work from the mobile app)
• On the left sidebar, click the + next to "Other calendars" → From URL
• Paste the converted link and click Add calendar

Your iCloud calendar now appears inside Google Calendar.

The Important Limitation: This Is Not True Two-Way Sync

Here's where many people hit a frustration wall. The iCal subscription method only pushes iCloud events into Google Calendar — it does not sync changes back. If you add an event in Google Calendar, it won't appear in your iCloud Calendar through this link.

Additionally, Google Calendar doesn't refresh iCal subscriptions in real time. The update interval varies — typically anywhere from a few hours to around 24 hours. If you need your iCloud events to appear immediately in Google Calendar, this method will feel laggy.

Third-Party Tools Fill the Gap 🔄

If you need reliable, real-time, bidirectional sync between iCloud and Google Calendar, third-party sync tools exist specifically for this purpose. Apps and services in this category work by connecting to both calendar APIs and keeping events consistent across both platforms.

The tradeoff is that these tools:

• Usually require account access permissions for both Google and Apple/iCloud
• May involve a subscription cost
• Vary in how they handle recurring events, event deletions, and calendar-specific rules

How much that matters depends on how many calendars you're managing, how frequently events change, and how much sync lag you can tolerate.

Factors That Affect Which Approach Works for You

Your primary device ecosystem plays a big role. If you're mostly Apple-based and only need to check into Google Calendar occasionally, adding Google as an account inside Apple Calendar may be all you need. If you live inside Google Calendar and just want iCloud events visible there, the iCal subscription route — despite the delay — might be good enough.

Calendar volume and complexity matters too. A personal calendar with a handful of events per week behaves very differently from a work calendar with dozens of events, meetings, and shared invites that change frequently.

Privacy considerations are worth noting with the iCal public link method — while the URL is not advertised anywhere, anyone who has the link can view your calendar events. Some people are comfortable with that; others aren't.

macOS and iOS versions can affect where settings live and what account options are available, so if a menu path doesn't match exactly, a quick check of your current OS version usually clears up the confusion.

The combination that's right for any given person depends on which direction they need events to flow, how much latency they can accept, and how deeply integrated they want the two ecosystems to be.
