The expression "night and day" is used to describe something that is very different and opposite from each other. It means that two things are completely opposite or different from each other, just like how night and day are completely different from each other. It can be used to describe a drastic change or improvement in something, or to highlight the stark contrast between two things. For example, "Since he started working out, he looks and feels night and day better." If you want to show how different two things are from each other, you can use the expression "night and day."
