Blogger Archive Calendar

Comments and Problems can be reported at the home post for this at
Blogger Archive Calendar

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.

Step #1
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.

Now, we need to copy and paste the scripts themselves. If you have an external server, you can copy the following scripts (removing the beginning /ending script tags) and save it as a file with the .js extension, then link to it from the head section. If that doesn't make any sense to you, don't worry. Just do it this way.
Find in your template the ending ]]></b:skin> tag  and the ending </head> tag. It should look something like this in your template



I've highlighted them to show them off. But you want to copy the following code, and paste it in between these two tags. Here's what you need.

<!-- End Blogger Archive Calendar -->

As of May 4 2007 the scripts will autodetect your timezone settings. Nothing here has to be changed, but there are a few things that some people may want to configure (especially non-English blogs) but for now the defaults will do.  If you want to change some things (especially if you have a non-English blog) then check out the full list at the Blogger Archive Calendar Settings Page

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.

To style the calendar, you can add some CSS entries. I've made up a few default styles to choose from. If you are knowledgeable in CSS than you can use the base ones to come up with your own. Or you can pick from what I've already whipped up ( I may add a few more as time goes by). All the styles I currently have are on their own page, with instructions on how to use.
