The difference between Occupation and Profession in English

The way you earn a living. It is the job you are paid to do. Think of it as the activity that “occupies” your time and from which you receive money for doing it.
Occupation is a formal word for job.
In a perfect world, your profession and occupation (or job) are the same thing. Unfortunately there are people that have a profession but work in something completely different.
