Abstract: University is the home of experience that serves teaching of undergraduates, research of postgraduates and serving the community and the environment. Experience supply, exchange and broadcasting is one of the main aims of it. The scientific days or meetings are an important method of teaching, learning and experience exchange in all scientific fields.  It is considered one of the main activities of different scientific departments at universities. The overall number of scientific meetings or conferences is generally much less frequent than lectures, but it is still a very important activity that has its own regularities and steps that every researcher or staff members needs to know. The scientific day is considered a small form of scientific conference with the same goals and principles.  This article aims to be a guide explaining the basics of essential steps to regulate an effective scientific day or meeting, which are also essential in scientific conference instruction. Organizing companies are not enough to be the only ones completely responsible for this process, but different members of every department of different faculties should be aware enough of these details.
