The changes are pushed and working in staging, the tests are passing, Q&A is done. Why hold off? So that you get your Good Practices™ badge? I'd say it's better that you don't have to deal with last week's work on a Monday if at all possible.
I think being down to earth, and keeping your good judgement is key. I don't recommend making world-shattering changes on a Friday, but even then, well, it really depends on the circumstances.
