All of the discussions I have read (I think all, I can't recall any others) here are about the legalism of the law on the sabbath. What God tells us in the Word is that it is the heart of the law we are to honor. To that end, let me try to answer your question from the standpoint of what the Biblical teaching is.
First, we understand that the world will change. It will become increasingly more sinful this is something that we can and should fight but will not be able to stop. The earth has been sinnful before and at it's worse, God destroyed the earth (Noah and the flood). So when we talk about honoring the sabbath, we start by understanding that as our world changes, those who are not true believers, committed christians will allow some sin into their lives and thus break the commands of God, even to the extent that they find a way to justify these sins. Sabbath is an easy one for this purpose and can easily be justified simply by argueing perifrial issues like what day of the week the sabbath falls on.
Second, let us look at what the sabbath is. To find this answer, we can go back to the beginning of the world. God created 6 days and rested 1. The idea of sabbath and even the command for sabbath, predates the calendar and as such, the discussions on which day of the week the sabbath is are sensless for it changes the focus from what the purpose of the sabbath is, easily allowing one to justify the sin of not having a sabbath. By the way, the sabbath is not set aside as a day to worship which we in this society emphasis, but rather as a day of rest from the labor we do.
This brings us to three, it is a day of rest. The pharisees of OT were repremanded by Jesus for making the sabbath a set of rules. They failed to understand the heart of the teaching, therefore to understand the sabbath, we dare not base our understanding on the OT law of what is and is not allowed. The heart of the law to have a sabbath is that we observe a day of rest from our labor. It is a day to renew ourselves and prepare ourselves for 6 new days of work.
When we understand these things, then to argue about whether or not I keep the sabbath, you must understand whether or not I take one day a week to rest and relax and veg, and enjoy being alive. This can occur any day of the week and I can do any number of things on that day. What I cannot do is my labor, my job, nor can I ask my household to do their labor. When it comes to fixing meals, if I fix the meals all week long, then I have my husband fix them, or cook ahead of time, or eat out at a restaurant that allows their employees days off. Other teachings and arguements are tradition and pull our focus from the truths of the teachings. The true believer, worships God, not tradition.
