Follow the instructions on the glue bottle. Titebond only needs to be clamped for 30 minuts, then you can start working with it. Just don't stress the joint, sanding off the glue excess won't hurt it, just don't string it up. Waiting until Friday is pointless.
Remember, the instructions on the bottle are there for a reason, the manufacturer wants you to succeed.
Just as a side note, I had a bookmatched piece of mahogany I was working with, 3/4" thick. I wanted to test the instructions, so glued it, ate lunch, came back took off the clamps, then bandsawed out a profile. No breaks. Then, I took a drop, and broke it right on the joint over the edge of a workbench, and the wood broke, not the glue joint. Remember, it was 3/4" thick, and it still broke the wood. That was after about an hour of dry time. Wood glue is not joke, Alphatic glue actually welds glue together.
