As a priest, I can say that no two days are alike. As mentioned above, every priest will have a different experience based on his personality, circumstances, parish, and other conditions.
I'll share what I did today as an example:
I got to the church office this morning after dropping the kids off at daycare, and went to work on the bulletin, answer emails, etc... Once I finished that, I worked on a presentation on "participating in Great Lent" that I will give to the church ladies' group next week. By that time, it was lunch, so I ate, then went to the hospital to pray for, annoint, and commune a sick parishioner. From there, I went to bless the home of another parishioner, and returned to the office to finish up the bulletin. Then I called it a day.
Some days, I hardly have anything to do; other days are full from 9 AM-9 PM, it all depends. I am the assistant pastor at a very large parish, and I usually work 6 days a week. Sometimes I put in 35 hours a week, sometimes 60, again, it all depends on what's going that week.
Regardless, I don't know of too many priests who aren't busy. Please pray for your priests.
