This is for New Blogger using Layouts templates only (blogspot or custom domain). Classic Templates not supported.
As with any template modifications, always make a backup before preceding !
Also, feeds for posts must be enabled in your settings (Blogger>Dashboard>Settings>Site Feed> Post Feed can either be set at Full or Short). Private blogs do not have feeds, so they are not supported.
Go to Template>Edit HTML. Leave the Expand Widget Templates box UNCHECKED (default)
This code will replace your Archive widget. Scroll down and find yours in your template. Will look something like this.
Copy the following code, then highlight the archive widget as shown and replace it with a paste.

At this point you may want to save the template. It should save without any errors, if not then make sure you followed the above, and copy/pasted correctly.
Find in your template the ending ]]></b:skin> tag and the ending </head> tag. It should look something like this in your template
Copy the following script, and paste it in between these two tags. Here's what you need.

Now save your template. It should save without errors, if not recheck your steps above. One more thing needs to be configured in your Archive Widget. Goto the Page Elements page, find your Archive Widget, and click to edit it. You'll see a screen like this
The title can be anything you want. The style MUST be Flat List as show. Options should NOT have Show Oldest Posts firsts checked. Archive Frequency MUST be Monthly. The Date Format can be anything you want. The calendar will accept whatever you decide here.
Save the widget. Then try it out. Go view your blog and if everything is correct you should have the calendar working now.
If you've made it this far, and it's working you'll note that without any style associated with it the calendar is a bit plain. But we've got some of that covered as well. Admire your work so far. Make sure it seems to function.
Good Luck
