This really is just a matter of personal preference. There is no right or wrong day for a pastor to take off. However, these are some of the benefits I have found with Mondays being my day off.
1- It allows time to recuperate from Sunday.
Sundays are wonderful, but long and draining days. The mental and emotional toll of preaching multiple times, spontaneous counseling sessions, and other meetings all make this the most tiring day of the week. By doing nothing church-related on Mondays, I have the needed time to recuperate before diving in to a new week.
2- It lines up with many school holidays.
Many of the holidays that schools acknowledge are celebrated on Mondays. Presidents Day, MLK Day, and Labor Day, are examples of this. By taking Mondays off I am able to spend these days with my kids without having to take an additional day off work.
3- It gives time to process ‘Sunday’ before making adjustments.
A lot takes place on Sundays, both positive and negative. In one day a pastor will receive praise and criticism. On one Sunday there will be things for which the pastor is excited, and other things about which he will be discouraged. Things will take place that need to be built upon, and things will happen that need to be changed. On any given Sunday attendance may be way up or it may be way down.
Immediate reaction to any of these realities is unwise. There needs to be time to process all that has taken place. I have found that by taking Mondays off and not addressing anything until Tuesday, I have the time to process everything accurately, see it for what it really is, and then make a level-headed determination about what needs to happen.
Again, this is just a matter of personal preference, but I have found these three things to be real benefits. Are there other benefits to taking a different day off? Sure. Are the negatives to taking Mondays off? Absolutely. You know yourself. Determine what will work best for you and your family and then be intentional about protecting that day off.
