I noticed whilst adding posts predated to the 1970s that the standard Blog Archive widget would not display the posts prior to 1990. This was really annoying. How could I fix this problem? Well, searching the Internet I came across a tutorial for converting a standard blog archive widget into a blog archive calendar widget. I thought I'd give it a try to see if it works.
I've added blog archive calendar widgets before and they weren't impressive. But after adding all the code to another template I now have the 1970s posts being displayed. It solved my problem and it came with a bonus - you can actually customize the look of the calendar to make it match the look of your blog.
Having posts dated prior to 1990 on Blogger is a bonus because you can put unimportant information in these posts and people generally won't go looking for them in your blog archives widget.
Anyway, hop over to the bloggerstop.net site and check out the tutorial. Its really simple to follow, and the widget is easy to instal.
