On that note (posted 11/24 but let's pretend it was posted in Sept.):
Despite many of its users' requests, Blogger does not give the option to sort posts in ascending/descending order. Toward the end of the semester, our teacher told us to change the post dates to change the order of these posts. I've searched the Blogger help files and this was the ONLY feasible way to do this (sad but true) and many users have requested this option.
Therefore, do not trust the automatically assigned post dates because they've all been changed. Instead, go by the posted date in the titles (I'm pretty sure they are correct).
