# Bidirectional synchronization with Google Calendar

**What is bidirectional synchronization with Google Calendar?** It means that all **bookings** your customers make in TuCalendi are added to Google Calendar. In addition, if you manually add any kind of event or task in Google Calendar, the system checks it against the **time availability** of the events you have created in TuCalendi. If the times overlap, those time slots are removed from your online calendar so nobody can book them, which **avoids conflicts**.

**Setting up this TuCalendi feature is very simple**. Once you have completed the [integration of TuCalendi with Google Calendar](https://www.tucalendi.com/en/s/integrations/connect-google-calendar-with-tucalendi) so that your events are synchronized between TuCalendi and Google Calendar, you need to [connect the events](https://www.tucalendi.com/en/s/availability-configuration-events/synchronize-an-event-to-google-calendar).

Log in to TuCalendi with your username and password and go to the **"Calendars"** option.

**Find the event** you want to synchronize with Google Calendar and **click on the event name**.

All the **event configuration options** appear in the horizontal menu.

Click on **"Synchronization"**.

Under the **"Google Calendar"** option, in the field **"Select the calendars to be checked for conflicts and avoid double bookings"**, click **"Add"** to choose the calendars you want to use for the bidirectional synchronization between TuCalendi and Google Calendar.
