That is a tough question to answer. The short answer is that for many, if not most engineers, every day is different. That is what I like about being an engineer. But remember, there are very many types of engineers: civil, mechanical, electrical, chemical are the major ones But, each of the major types have specialty or a sub-groups (i.e. aeronautical engineers are a sub-group of mechanical engineers, computer engineers are a sub-group of electrical engineering). But, regardless of the type of engineer as listed above, there are different functions that an engineer might perform. There are design engineers, manufacturing engineers, field (construction ) engineers, quality control engineers, test engineers, sales engineers.
I guess that you asked the question because you are trying to decide on what type of engineer you would like to be. My suggestion is that you go on the Internet and Google the various types of engineers that I have listed above to get an idea of what types of work each does and what seems most interesting to you. For example civil engineers design and construct things that don't move (buildings, bridges, roads) while mechanical engineers design and construct things that do (automobiles, machinery, engines, ships, mechanical systems). Once you decide on which type of engineering, do you want to be a designer who works with design programs and works mostly in an office or a manufacturing or field engineer who implements the design of the design engineer and actually builds something.
As I said above, not an easy question to answer but, the important thing is to find something that interests you. A typical engineer will be working with people, doing some paper work, going to meetings, talking on the phone and most importantly, solving problems.
Hope this helps,
