Is the promotion worth it?

I stayed late at work today because one of our two team leads called in and several people left early.  Normally team leads come in two hours early and can stay two hours late or even more.  Going home early is not an option.  Even with a four day workweek, I have to rethink about is it really worth it.  The pay raise is significant and would put me over $20 an hour for the first time in my life.  But 11-13 hour days every day at my age might be too much.
