Your date format is different from the proposed one. To make things easy, you should be using this one:
20110905 20111015 20111016 20111017 20111018 20111019 20111020
Then, just generate the string for the day 45 days ago and remove everything lesser.
How to find what that days' date was? How yould you proceed without a computer? Would you calculate the date, or just have a look into a calendar?

    This is exactly the right idea! The file names shown will sort with a simple string comparison based upon the text from the file name. I am at a loss as to how to make this more clear.

    Working with the filename is just much easier and more obvious than working with OS specific things like the -M file test.
