How to Sync Your Google and iCloud Calendars: 3 Easy Ways

The Gist

If you're struggling to keep your Google and iCloud calendars in sync, you have a few options to get organized and stop getting double-booked:

Subscribe to your Google Calendar (View-Only). This lets you see your Google events on your Apple devices, but you can't edit them, and the updates can be slow.
Add your Google Account to your iPhone. This is an easy way to see both calendars side-by-side on your phone, but it doesn't actually sync them.
Use a real two-way sync tool like Caltsu. This is the best option. It provides a real-time, automated sync between your Google and iCloud calendars.

Juggling multiple calendars between Apple and Google can be a nightmare. Because these two tech giants keep their worlds separate, syncing your events isn't as simple as it should be. If you're tired of missing meetings or double-booking yourself, it's time to sync your Google and iCloud calendars. Here are three ways to do it, from the free DIY options to a seamless, automated solution.

Why Don't Google and iCloud Calendars Sync Automatically?

Apple and Google calendars don't sync with each other because they use different systems and they want to keep their data separate. When you add a Google Calendar to your iPhone, you're only getting a view of it in your Apple Calendar app—the two are not actually merged. This means that an event on one calendar won't show you as busy on the other, which can lead to scheduling conflicts.

To truly sync your Google and iCloud calendars, you need a bridge to connect them. Let’s look at your three best options.

This is a classic workaround that lets you see your Google events on your Apple Calendar on a Mac or an iPhone.

The catch: It's read-only. You can't edit your Google events from your Apple Calendar, and the updates can take up to 24 hours to appear.

How to get your Google Calendar link

Open Google Calendar on your computer.
Hover over the calendar you want to share and click the three dots.
Choose Settings and sharing.
Scroll down to Integrate calendar.
Find the Secret address in iCal format and copy the URL.

How to add the link to your iCloud Calendar

Open the Calendar app on your Mac.
Go to File > New Calendar Subscription.
Paste the URL you copied.
Click Subscribe.
You can rename the calendar and choose a color.
Set "Auto-refresh" to the shortest time allowed.
Click OK.

The limitations of this method

It's view-only, so you can't edit events from your Apple Calendar.
The updates are slow (up to 24 hours).
Other apps won't see you as busy for your Google events.

If you need to prevent calendar conflicts, this method isn't going to be enough.

Method 2: See Both Calendars on Your iPhone

This is the most common way for iPhone users to see all their events in one place. It will display both calendars in the iOS Calendar app, but it doesn't actually merge them in the cloud.

How to set it up:

Open Settings on your iPhone or iPad.
Go to Calendar > Accounts > Add Account > Google.
Sign in and turn on Calendars.
In the Calendar app, make sure your Google account is checked.

The downside

This is just a visual overlay. It's not a true sync between Google and iCloud.
Other people will not be able to see your Google events when they check your iCloud availability.

Method 3: Use a Real Two-Way Sync with Caltsu

For a real sync that mirrors your events between Google and iCloud in real-time, you need to use a dedicated tool like Caltsu.

Why use Caltsu?

It instantly syncs events both ways.
It prevents you from getting double-booked by blocking off your busy time slots.
It lets you choose your privacy settings for each sync.

How to Set Up a Google-iCloud Sync with Caltsu

Create a Caltsu account (Start your free trial).
Connect your Google and iCloud calendars.
Create a sync:
- Choose your Source (Google or iCloud).
- Choose your Destination (iCloud or Google).
Set your privacy options:
- Busy only (shows the event as "Busy" on the other calendar).
- Full details (syncs the event title, location, and description).
Repeat the process in the other direction for a two-way sync.

The benefits over other methods

Real-time updates—no lag.
Conflict prevention—all your calendars will show your true availability.
Privacy control—you can choose what information is shared.

Which Sync Method Is Right for You?

Use Method 1 (Subscription) if:

Your schedule doesn't change very often.
You're okay with slow updates.
You don't need other people to see when you're busy.

Use Method 2 (iOS Settings) if:

You only check your calendars on your iPhone.
You don't use scheduling tools.
You don't need to share your availability with anyone.

Use Method 3 (Caltsu) if:

You manage both work and personal calendars.
You use scheduling links (like Calendly).
You want privacy and a real-time sync.
You want a solution that you can set up once and forget about.
