I know events added in Google Calendar can be accessed in other applications (e.g. iCal) by connecting to Google's CalDAV server. But I have my own CalDAV server to which people add events with a variety of applications, and I was wondering whether Google Calendar can automatically import (and stay in sync) with these events, presumably by connecting to my CalDAV server? I can't find any reference to this in Google's help pages.

If you publish an iCal/xCal file to your website then your users can subscribe to this using Google Calendar. In the Calendar UI its under Settings->Browse Interesting Calendars->Add by URL.
This causes Google to internally create a new Google calendar and arrange for it be populated with new events from your feed regularly (at least once every 24 hours). To add new events you simply upload/publish a new version of your calendar file.
If its a bit much to ask your users to follow this method, then you can publish a "subscribe to calendar" link or button on your website. The link should be:
http://www.google.com/calendar/render?cid=http://location-of-calendar-file
Or for Apps:
http://www.google.com/calendar/hosted/somedomain.com/render?cid=http://location-of-calendar-file
Google used to have this information in a support document but I can't find it anymore :( I can verify that this method works well - we publish personalized feeds for 150K users right now.
You can get an iCal link for your Upcoming Events (or Birthdays) that you can import into Google Calendar which will automatically stay up to date.
In Facebook:
- Go to your Events.
- On the left sidebar, click Calendar
Go to the lower right portion of the page, where you'll see a message with two links:
Save the URL for the Upcoming Events link. (This will vary by browser/OS, but is generally something like right-click and Copy link address)
The URL should be similar to:
webcal://www.facebook.com/ical/u.php?uid=999999999&key=AbCDEf12345AAcd-f
(Your actual uid and key values will be different, of course.)
In Google Calendar:
Scroll down and open the Other calendars menu (on the left)
Choose Add by URL
Paste the webcal URL in the URL space then Add Calendar
You should now have a calendar {Your Name}'s Facebook Events listed under Other Calendars and can change the color, details, etc. as needed.
