Common refers to something that is frequent, usual, or shared by many, whereas normal pertains to what is typical, standard, or expected in a given context.
Key Differences

Common can be used to describe shared characteristics or experiences among a group, signifying similarity or ubiquity. Normal is often used to describe what is customary or regular, indicating conformity to an established pattern or average.

Something common may not necessarily be normal; for instance, a common cold is widespread but not a normal state of health. Conversely, something normal is not always common; for example, a normal body temperature can vary from person to person.
