I very much doubt that you are absolutely certain. There are a number of outlandish but not impossible worlds in which you could believe that it is Friday, yet it might not be Friday; something akin to the world of The Truman Show comes to mind.

Unless you believe that all such alternatives are impossible, in which case you may be absolutely certain, but incorrectly so.

I don't have to believe that the alternatives are impossible; I just have to be certain that the alternatives are not exemplified.
