Added a Calendar

Blogger doesn't have a built-in calendar, which seems so strange because all Japanese blogging sites have a calendar built in.

But I wanted one, so I did a quick Google search for "blogger calendar" and I came across a guy who built one.

I really don't like reading instructions, but he made it pretty simple to set up. Now I just have to figure out how to make it green... He has a pre-made color themes for blue. I guess that's a popular color. His calendar is green, but I don't need the gradation.
