Embedding a Calendar in Google sites - required step is sharing calendar first

If you're going to embed a calendar in your Google Site, you have to make it public.  You can do this by following these directions:

Click "Calendar" in the black bar at the top after you've signed into Google Sites or your e-mail

Find the calendar you're wanting to embed (or that you've already embedded), and hover your mouse to the right of the calendar's name.  A small triangle will show up, click it once to access a drop down menu

On the drop down menu, click "Calendar Settings"

On the page that shows up, click Share this calendar, near the top under the name of the calendar

On the sharing tab, check the box for "Share this Calendar with others"

Also check the box for "Make this calendar public" and choose "see event details" from the drop down menu to the right

Click Save to save this change.
