Evolution with Google Calendar and Facebook Events

This is something that will be useful only to people who use Evolution (as I said at first, my second OS is Ubuntu).
The other day, while examining my desktop calendar, I wondered to see if I could somehow sync with Google Calendar, and not only I managed to do that, I also synchronized the calendar with Facebook Events.
Photo of my success:

As you'll know, I use Ubuntu in spanish of course.

By the way, the orange icons are Google Events and the blue ones are Facebook Events.
First things first...

Let's start configuring Google Calendar. Let's go to Evolution (can do so from console or searching Evolution, or directly from the desktop calendar). You maybe see "Evolution Mail", but the calendar is out there (see the image below): 

Again, and screenshot from my spanish Evolution.

Now go to New/Calendar. From there, we have two paths, add the Google Calendar or Facebook Events, let do the first:

• Type: Google. 
• Name: A name to identify it (eg Google). 
• Color: Personally, I chose orange for Google, but it's in you. 
• Mark the first option (the sync thing). 
• User: Your username Google, without the @gmail.com (eg john@gmail.com -> john). 

The other options I leave you to your own experiments... And presto, we have the Google Calendar ready. For Facebook Events is a little more complicated (just a little, not more). Same procedure (New/Calendar), but this time we chose...

• Type: On The Web. 
• Name: The name identification (eg Facebook). 
• Color: As I said before, I chose blue for Facebook. 
• One more time, mark the option to sync. 
• URL: Let's go to facebook events page, and at the bottom we'll find the Export option. Copy this link and paste it here. 
• The option of SSL goes beyond my knowledge. Is up to you (I didn't check it). 
• User: Your facebook user (the one you used to login on Facebook). 

It should be noted that you have to type a password before the Calendar can sync.
And presto, that's it, you have configured the Evolution Calendar. 
You'll discover that it's very easy to set more calendars, but I only had these two, so my tutorial ends here.
Evolutioned greetings.
