The easiest way to add a meeting to your calendar is to rely on the meeting confirmation email you will receive after booking the meeting. It is structured to be recognised by major email providers as a meeting invite, so you should be able to click on "add to calendar" to have it added to your calendar.

You can also download a meeting file (.icf) from Ovida and then import it to your calendar. The meeting files can be accessed from the Home page.

Importing differs by calendar (Microsoft Outlook, Google etc). Your calendar's help section will describe the process.
