The best way to embed a calendar is to sign up for and use the 'Google Calendar' widget. It is very powerful and allows you to add reminders and add reoccurring events.
I found the Calender widget and the source code for that is:
Get the Google Calendar widget and many other great free widgets at Widgetbox! Not seeing a widget? (More info)
I don't see the calendar on the page. I tried pasting it into the html editor as well as pasting it in with the "insert hyperlink" button. Suggestions?
I think you need to sign up for a Google email account (if you have not done so already). There, in your email account, you will have a Calender you can use. Go to the calender and there you can fine the option to insert code into your website that shows your calender.
Widget box is a third party widget that adds an extra middle man to the process that you really don't need for this calender...
