Connecting Google Calendar lets Cal.com check your Google calendars for existing events before it offers a time, and add every new booking to the calendar you choose.

## Prerequisites

- A Cal.com account.
- A Google account that holds the calendars you want Cal.com to use.
- Permission to let Cal.com view and edit those calendars.

## Steps

### Step 1: Install Google Calendar

Open **Apps** in the sidebar. Type `Google Calendar` in the search box, then click **Install** on the **Google Calendar** card.

Cal.com then sends you to Google to approve the connection. Approve access for the Google account that holds the calendars you want Cal.com to use, and Google returns you to Cal.com when it finishes.

### Step 2: Choose which calendars to check for conflicts

Open **Settings** in the sidebar, then **Calendars**. Under **Check for conflicts**, turn on the calendars Cal.com should watch. Cal.com will not offer a time that overlaps an event on a calendar you turn on.

### Step 3: Choose where new bookings go

Under **Add to calendar**, open the **Add events to** menu and select the calendar that should receive new bookings.

## Tips

- Turn on shared and team calendars as well as your personal one, so Cal.com never offers a time that is already taken.
- Leave a calendar turned off when you do not want its events to block your availability.
- You can send new bookings to a different calendar for one event type only, in the advanced settings of that event type.

## Summary

Once Google Calendar is connected, Cal.com checks it for conflicts and writes every new booking to the calendar you selected. Both settings stay on **Calendars** in your account settings, where you can change them at any time.
